<pre>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:
