Xpra: Ticket #458: Client area resize occasionally out of step with window resize

This seems to be a lot worse running the client under KDE/Kwin. I assume a message is being lost somewhere along the way. It really only happens when I resize the window back and forth very rapidly between small and large and try and let go before the client has caught up. You might describe it as a forced error but I'm pretty sure if I can make it happen by abusing the resize it will also happen occasionally during normal use.

I don't know whether this is fixable by sending an additional message on mouse up after checking if the window size has altered or if there are any other messages or hooks that could be used for the same effect.

Anyway perhaps when there are no other bugs to look at you can look at this one :)

Actually thinking about it I only started to check if there was an issue because I saw a thick black border inside the window after resizing one time.

Probably related to #252 and #107

Unless KDE/Kwin is very broken (which I doubt), we are already getting all the events that we should. The problem is more likely to be a race between the client resizing and the application re-configuring or re-sizing itself in response to those changes: this is inherently racy. Each end runs with its own X11 server time so there is no easy way to synchronize events and decide who is right.

This is not a regression, so tentatively scheduling for 0.12

Is this fixed in 0.10.x or 0.11? #252 was reported as being fixed.
