Xpra: Ticket #790: Windows is continous flashing in loop

Reproduce:

  1. Server (Ubuntu 12.04), Client (Windows 7), xpra 0.14.18 r8503
  2. Start and attach xpra with tcp
  3. Open Firefox or something.
  4. Minimizing and restoring a Firefox window very quickly until the system got stuck in this loop, continuously flashing the window.

Can you reproduce with something else, like an xterm? Or does this have to be firefox?

It really does sound like the bug that I thought I had fixed in r8336 / r8387. (which is also responsible for the chrome window's lack of responsiveness from the system tray)

Replying to totaam:

I'd just reproduce with Opera, Thunar and xterm( it seem hard to reproduce ) and this bug still occur. I can't reproduce Chrome because it can't minimize by click in it from the taskbar


Fri, 23 Jan 2015 04:14:44 GMT - Antoine Martin:

OK, I can't reproduce it here - not sure why.

I'm sorry for very late reply. I forgot this... I'm using xpra beta 0.15 r8603, and splash still occur. This issue occur when:

  1. Minimizing and restoring a Firefox window very quickly until the system got stuck in this loop, continuously flashing the window, as I described before.
  2. Sometimes, when I opening a Firefox (Firefox is crashed before), this issue also occurs. I can't reproduce this case.

Wed, 04 Feb 2015 10:14:13 GMT - Antoine Martin: owner changed

I couldn't reproduce it here - could be because when I test my server latency is lower? So r8618 attempts to take the server latency into account to know how long to wait before it should be safe to send the "unmap" (iconified) message.

Can you post your:

xpra info | grep latency

If it happens again, can you please try with -d window,state, I've added the "state" debug flag to track problems like this one.

It still occurs again. This is how I reproduce:

  1. Attach xpra with tcp
  2. Open Firefox.
  3. Left-click on Firefox button from taskbar as fast as I can, until the problem occurs.

I know that 3rd step is deliberate, and maybe no one do that. But as ticket:790#comment:5 I can't reproduce clearly the 2nd case, and I think 2 case are the same reason.

Maybe, but it's still a bug and we want to fix it. Thanks for the logs. I think can see what is happening: we are caught in a loop with the maximized state toggle as well as iconified. Those are sent and handled separately, which may be the cause of these problems.


Thu, 05 Feb 2015 05:13:22 GMT - Antoine Martin:

Got it, I had to make the window maximized first to reproduce the bug, otherwise I just could not hit it.

r8623 fixes this for trunk, backport to v0.14.x in r8627. New beta builds uploaded for both versions.

@John1221: can you still break it somehow?

OK, thanks. Closing.

I assume that those new tickets are not regressions caused by this fix?

I am unable to reproduce it (maybe due to having different network parameters, especially latency), but maybe r8661 fixes this? (it could be backported as it is relatively harmless - I think)

If not, please post the client output with -d win32,metadata. It looks like a race between the client and server each trying to (un)maximize the window, I just don't see what causes it, yet.

I have uploaded new beta builds with this change (you will need both a beta client and a beta server to test this change). Note: no Ubuntu 12.04 builds... I'm not even sure that it will be supported in the final release. Time to move on.

Lots of updates, found some minor bugs along the way too:

@John1221: I have uploaded new beta 0.15 builds with those fixes (centos 6.4, 6.5 and 6.6, and MS Windows - more builds later), does that help? (you may need both an updated server and an updated client to be able to test all those changes - though obviously this should still be compatible with older versions and some of the fixes will work independently, it would actually be useful to know this so that I know what really needs backporting to the v0.14.x branch)


Thu, 19 Mar 2015 15:10:13 GMT - Antoine Martin:

r8802 fixes an embarrassing bug and also adds synchronization of more wm states (see #773). New beta uploaded.


Fri, 20 Mar 2015 23:56:05 GMT - alas:

Testing with win32 client 0.15.0 r8802 (your beta) against a fedora 20 0.15.0 r8806 (smo's build) server - I can't reproduce any flashing loop error with firefox (created as a start-child or from a start-child xterm).

I was able to get the firefox to take over top-level focus and refuse to respect any other application, mentioned in #773, but it's no longer reliably reproducible?

One odd detail (well, technically two), maximizing the firefox window on a 4k monitor and playing video while trying to min/restore/min/restore I find that after about three restores the firefox window begins restoring not to maximized dimensions, but rather to the pre-maximized dimensions... and the speakers are sporadically turned off as well (seems random, using the tray to check speaker status shows it to have toggled to "off", switching back to "on" restores sound).

I noticed a couple of tracebacks and messages on server-side... but I'm not certain that they relate (or at least whether or not the all relate) to the sound issue (my guess), so I'll put them here for now.

Not sure if -d win32,metadata is liable to be of much use here... and the client outputted nothing unusual, just messages about re-starting the speaker.


Sat, 21 Mar 2015 04:43:37 GMT - Antoine Martin:

The AttributeError: 'NoneType' object has no attribute 'source_has_more' error should be fixed in r8807. (it was probably harmless)

What is happening there is that as you generate lots of large screen updates (maximizing / restoring large windows), you are generating so much traffic that the sound goes into underrun / overrun and restarts. Were you using the default queue settings? Maybe add -d sound on the client side to see the sound queue levels when the sound gets restarted.


firefox window begins restoring not to maximized dimensions, but rather to the pre-maximized dimensions...


I don't think we really need to worry about this one, do you?


I was able to get the firefox to take over top-level focus and refuse to respect any other application, mentioned in #773, but it's no longer reliably reproducible?


Well, it sounds like it is if you've just reproduced it!?

PS: probably the same fix as #809.


Tue, 24 Mar 2015 03:56:10 GMT - John1221: owner changed

@totaam: Great. It's work. And like afarr described, Firefox windows state changed from MAXIMIZE to NOT-MAXIMIZE (maybe NORMAL state ? ), but I don't worry about this.


Tue, 24 Mar 2015 16:45:52 GMT - alas:

Tested one more time to see about the firefox refusing to yield top level focus... couldn't reproduce with windows client 0.15.0 r8002 against a fedora 20 server 0.15.0 r8006.

And no, I can't imagine the switch to non-maximized being a problem for anyone who toggles min/max/min/max enough to cause it (methinks such users have other issues to keep them busy).

Seems good to close.

I've tested with 0.14.22, installed both client and server. And with 0.15 ( again ). It will be work if my mouse click speed is normal, or faster a bit. But if the speed is very fast, like https://youtu.be/ylqkCXCHqdM?t=46s , the window will be flash in loop again. I found a video from youtube to describe my speed clicker. In that case( very fast), nobody will do that. Just it's still appeared, and I response. We don't need fix anymore.

I have tested again with the server ( trusty, xpra 0.15 r9016), client ( MS Windows 7, xpra 0.15 r8987). And this problem occurred. Reproduce:

  1. Server-side: xpra start :100 --start-child=xterm --bind-tcp=0.0.0.0:1000 --no-cursors --no-pulseaudio --no-speaker
  2. Client-side:
    • Attach xpra : Xpra_cmd.exe attach tcp:IPADDRESS:1000 -> A xterm appears.
    • Open a Firefox from the xterm.
    • Maximize the Firefox, maximize the xterm.
    • Minimizing and restoring the xterm window very quickly by mouse click from the taskbar until the problem occurs.

Thu, 16 Apr 2015 08:56:17 GMT - Antoine Martin:

John1221: is this a regression from previous 0.15 beta builds? Or does this still require super-fast clicking to trigger? (if this is a regression, it may have been caused by r9009 / #809).


Thu, 16 Apr 2015 09:49:32 GMT - John1221:

@antoine: I think so. I've just tested r8988(server - Trusty) and r8987(client - MS Windows 7) and it still occurs. I feel we don't require super-fast clicking. I can reproduce quite easy.

@John1221: ideally I would like to know when I fixed it so that I could backport it to older branches... if/when you get a chance, can you try different win32 builds to try to identify the first known revision that fixed the issue?

As per ticket:809#comment:20, r10790 may be causing us problems in 0.15.x


Wed, 21 Oct 2015 10:06:55 GMT - John1221: owner changed

@antoine: I tried with many win 32 builds, but I can't reproduce this issue again. I used xpra 0.15.7 for server, and client: 0.14.22, 0.15.0 r8826, 0.15.0-r9202, 0.15.7-r10824... feel good. Then I changed xpra server to older versions(0.15.0-1, 0.14.22, 0.14.21, 0.14.19) and still good. Maybe the issue appear when I'm using xpra beta 0.15.x ( server or client ) instead of release versions ? Beside, please read ticket:765#comment:15 Thanks :)

I have this bug. It seems like regression, because we spotted this after upgrade from 0.14 to 0.17. Tested with the following setup:

Debian Stretch or Sid xpra 0.17.6+dfsg-1 or 2.2-20170812r16688-1 in default configuration (0.14.10+dfsg-1 is not affected) ratpoison window manager firefox 52.3.0esr-1~deb9u1

This sequence always reproduces the bug:

  1. Open some windows (tested with four) in firefox, then kill firefox, so it will ask to restore session on next start
  2. Start server: xpra start :20 --start-child=/usr/bin/xterm
  3. Attach for the first time: xpra attach :20
  4. Start firefox on xpra display and press "Restore session" button in firefox. Surprisingly, for the first time only it will successfully restore all windows.
  5. Detach from xpra session via Ctrl-C.
  6. Attach again: xpra attach :20

Screen will flash endlessly until xpra killed.

Please suggest any workaround, because this bug effectively prevents me from using xpra.

No, but the link you posted will go 404 at some point in the future, making this ticket useless. Also the logs are huge, I'm not going to skim 50MB of log files.

Please try a different window manager to narrow down the problem.


Mon, 21 Aug 2017 20:17:35 GMT - sa:

No bug when attached in xfwm4. The only strange thing in xfwm4 is that all firefox windows appear minimized after every attach. Ratpoison tries to maximize every window, this feature probably interferes with firefox's own size restore, but nevertheless causes no problem without xpra. What kind of logs are required to track down the issue?

Tue, 22 Aug 2017 09:32:57 GMT - Antoine Martin:

Looking at the logs, I see tons of:

map-window wid=5, geometry=(1, 1, 1678, 1048), client props={'workspace': 65535}, state={'iconified': False}

It keeps going back and forth between iconified and not for window ids 4 and 5, every few milliseconds. This doesn't look like an xpra bug. You can try adding "-d state" to the debug flags to confirm, I suspect these events are triggered from window_state_updated which is a signal we get from the window manager. This ticket was about a race condition between the client and server, but here xpra is not directly involved and is just being spammed with state updates.

Please attach the client debug log with "-d window" added, it isn't clear to me if the iconify / deiconify loop is triggered by the window manager or by xpra itself as a response to a map event.

You can also try this patch which may fix things:

--- xpra/client/gtk_base/gtk_client_window_base.py	(revision 16610)

             self.process_map_event()

This would prevent xpra from de-iconifying a window when it is mapped. (not sure why the window manager would map an iconified window... but whatever)

If that doesn't help then it means that we just get a storm of WM_STATE updates from the window manager (see ICCCM 4.1.3.1), we never even get a chance to tell the server about it. (the window manager toggles every few milliseconds, we tell the server after a variable delay, usually 150ms or above to prevent race conditions - that's what this ticket is originally about).

This is probably triggered by the windows being created all at the same time and all iconified. When running Firefox locally, your windows will not start minimized, and they will not be created all exactly at the same time. I can't think of another workaround, you would need to disable the calls to self.iconify() in the client window code until your window manager is fixed.

This should be fixed properly in r16722. @sa: please confirm so I can backport to older branches.

Can I wait till this version appear in https://xpra.org/beta stretch, or better download/install manually?

You should be able to apply r16722 by hand, otherwise I've just pushed some beta stretch amd64 packages.

I confirm the bug is fixed for me in v2.2-r16722 (with ratpoison 1.4.8, firefox 52.3.0esr-1~deb9u1). But, now the firefox/xpra windows are not maximized to fullscreen by ratpoison. In r16688 and earlier this happened sometimes, now it happens always. This is probably unrelated bug, so #790 should be closed.


Mon, 28 Aug 2017 15:07:23 GMT - Antoine Martin: status changed; resolution set

Please file a separate bug for "maximized to fullscreen", and point back to this ticket for reference. (especially if this changes how often the bug occurs - this can help narrow it down)
