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: https://bugs.kde.org/show_bug.cgi?id=349910

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

It can't be an r600 driver bug then.

Are you sure it's not a kwin bug?

Right, there is KWin report: https://bugs.kde.org/show_bug.cgi?id=361154
Seems like reproducible with proprietary drivers too.
