Corrupted title and borders
After launching games based on Source engine (and also Planetary Annihilation:
TITANS) windows titles and borders are corrupted and sometimes frequently
flicker (please look into attached screenshot). I guess this is happening with
combination of Source engine and KWin because Source engine ask compositor to
pause desktop effects (and probably PA do this too) and KWin honour this
request: <a href="https://bugs.kde.org/show_bug.cgi?id=349910">https://bugs.kde.org/show_bug.cgi?id=349910</a>
This issue in not reproducible with Unreal Engine or Unity3D engine based
games.
I using modesetting, DRI3, GLAMOR combination, but issue also reproducible with
other combinations too (with radeon, DRI2/DRI3, EXA/GLAMOR).
Most of the time I launch games via DRI_PRIME, but issue is also reproducible
when game is launched on iGPU.
AMD A8-3500M, Radeon HD 6620G iGPU
AMD Radeon HD 6650M dGPU
Kubuntu 16.04 x86_64
Mesa 11.2, 12.1 git</pre>
