Martin Steigerwald <mar...@lichtvoll.de> changed: What |Removed |Added ---------------------------------------------------------------------------- Resolution|--- |WORKSFORME Status|UNCONFIRMED |RESOLVED --- Comment #13 from Martin Steigerwald <mar...@lichtvoll.de> --- Okay, I think I found the exact circumstances that cause the issue for me. As said it is both sessions have compositing + GLX, but I additionally found that it only happens with DRI v3. I now commented out DRI v3 again like this: Section "Device" Identifier "Grafikkern" Driver "intel" # Option "Backlight" "/dev/null" Option "AccelMethod" "uxa" # Option "AccelMethod" "sna" # Option "TearFree" "true" # Option "DRI" "3" EndSection and two sessions now work stable again. I thought it would be kscreen as I had a quite nasty brightness to zero bug with it before that went away when deleten ~/.local/share/kscreen. This time it wasn´t kscreen. I am sorry. I am closing this one and opening a new one for KWin even tough it may be a driver issue, but then I think it is good Martin is aware of it.
