Description Daniel Drake 2019-08-13 05:42:46 UTC

When starting OpenArena fullscreen under GNOME, the screen becomes corrupt and the game is unplayable (see attached photo).

This has been reproduced on:
 1. Ubuntu Eoan 19.10 nightly using OpenArena from Flathub
 2. Ubuntu Eoan 19.10 nightly using OpenArena from Ubuntu packages after configuring it to enter fullscreen mode
 3. Endless OS 3.6.2 using OpenArena from Flathub

The same tests on machines that use i915 or amdgpu graphics do not reproduce the problem.

Back on the radeon device, I also found the problem does not occur if you first use xrandr to change display mode to 640x480 (so that running the game does not require it to change the display mode). Alternatively, configure it as:
   Option "DRI" "2"
and the issue is fully avoided (even when the game changes the display mode during launch)

This worked fine on older distro versions, so it appears to be a recent regression and I bisected it down to:

Please let me know how we can help debug further.

That change is over 2 years old, not exactly "recent". :)

Does it still happen with xf86-video-ati 19.0.1 or current upstream Git master?


P.S. Removing myself from CC, two copies of each notification from the mailing lists is plenty.

Comment 3 Michel Dänzer 2019-08-13 10:00:55 UTC

Please attach the output of glxinfo as well.

Comment 4 Daniel Drake 2019-08-13 10:03:15 UTC

Yes it still happens with git master and the 19.0.1 release.
I'll post the glxinfo output tomorrow. Thanks for the quick response.

How much older? The commit you bisected to would have been included as of Ubuntu 17.10.

Comment 6 Daniel Drake 2019-08-13 10:12:28 UTC

Endless-3.5.x (and also Debian Buster which was the base for that) has xf86-video-ati-7.8.0 and it works fine there.

Comment 7 Daniel Drake 2019-08-13 10:13:20 UTC

Sorry, I meant Debian Stretch

Comment 9 Michel Dänzer 2019-08-14 12:11:05 UTC

Don't forget to attach the Xorg log file as well, and the output of dmesg (captured after reproducing the problem) and xrandr (captured before reproducing the problem) for good measure.
