[Bug 1283820] [NEW] content of windows (and desktop) appear black when using kwin, but not with kwin_gles - intel graphics

[avlas]

Public bug reported:


When I start a session all my windows appear in black as well as my desktop if using kwin. This behavior is not entirely deterministic, it occurs about 75% of the times. I have an intel graphic card, and same thing happens no matter sna or uxa is used.

This doesn't happen if using kwin_gles instead (but I don't use it
because then the blur effect doesn't work). Please let me know if I
should fill a bug in kde as well...
