Description Luca Mastromatteo 2018-09-30 16:18:32 UTC 
That is not an annoying issue, but I've noticed the Kwin behaviour to disable desktop effects when an OpenGL game is opened, reducing lag and increasing FPS.

However, using Steam with the Steam Play function, or running a wine game, with DXVK or not, desktop effects are not disabled.
Seems like when a game is opened through wine, kwin does not detect it 

STEPS TO REPRODUCE
1. Open a wine game through steam play or just wine

OBSERVED RESULT
Desktop effects are not disabled like when running an opengl game without wine

EXPECTED RESULT
Desktop effects disabled

The game needs to indicate that compositing should be disabled.

Actually it's different than I though.

Native games disable desktop effects even if windowed, while wine games disable desktop effects only when on fullscreen..
