video rendering can break with xserver-xorg-video-intel (2:2.99.914-1~exp1ubuntu3) & opengl output

[Doug McMahon]

Test case:
On intel Haswell machine
Using default of opengl or setting to opengl-hq
Open a video in mpv (windowed ), the d. left click to make fullscreen.
Then d. left click to return to windowed mode. Video rendering will halt though audio will continue to play.
Sometimes takes more than 1 attempt.
Returning to fullscreen & rendering resumes

If done 10 times then around 80% will show this.

Downgrading to previous xserver-xorg-video-intel (and related xserver packages, ie., 2.99.914-1~exp1, xorg-video-abi-15) & this does not occur.
The --vo does matter, if switching to xv this doesn't occur

The same is seen in mpv git so not an issue just with 0.4.2

Hi,

I'm afraid I don't have a Haswell machine to test this on, and the bug is now a bit old. Can you try using a recent version of mpv and the Intel xorg driver (or even the modesetting driver)? If you can reproduce the bug with mpv git master, can you file a bug upstream?

Thanks,
James
