Xonotic screenshot showing corruption.
Kernel version doesn't seem to affect this.
mesa/drm are agd5f amdgpu git.
First test with DRI3 was xf86-video-amdgpu week old git on months old xorg
Now built new git xorg = same results.
Xonotic 0.8 glx settings/aa all high I see some corruption on menus and in game.
This only happens if DRI3 is enabled.
Might be fixed in http://cgit.freedesktop.org/mesa/mesa/commit/?id=6611f65047575054a38ce83ebfe0331e39e1774f .
Yes, that fixes it.
