Aka XPRA_OPENGL_FBO_RESIZE_DELAY
, added in r23338 for #2217.
There must be a more deterministic event we can wait for instead of using a timer. (which is not always long enough)
Could this be related to #2462?
See #2481: I believe the correct solution is very likely to be similar to the fixes from #2481, we have to use an expose event.
The backing knows nothing about the window, so hopefully we can just queue_draw_area
on the backing directly?
The delay does not seem to be needed any more, so r24463 makes it optional and defaults to -1 (disabled).
Mostly reverted in r24464 as the bug still occurs on win32.
Should be fixed in r24465.
Just needs re-testing on all platforms..
Damn. Still occurs on macos...
Could probably be removed after the latest round of opengl / gtk3 paint fixes: r24577 (+ r24581 + r24576), except macos uses the XPRA_OPENGL_CONTEXT_REINIT=1
default, see #2491.
Disabled by default in r24592 following ticket:2491#comment:10.
