With enabled compositing it looks like my screen is frozen, it doesn't do anything and mouse cursor is the only thing which is moving. Clicking on something actually do some action, but you can just guess what is going on as the display is not refreshed. Here is some output from KWin about my driver and so on: OpenGL vendor string: Intel Open Source Technology Center OpenGL renderer string: Mesa DRI Intel(R) Sandybridge Mobile OpenGL version string: 3.0 Mesa 10.4.0 OpenGL shading language version string: 1.30 Driver: Intel GPU class: SandyBridge OpenGL version: 3.0 GLSL version: 1.30 Mesa version: 10.4 Linux kernel version: 3.17.6 Requires strict binding: yes GLSL shaders: yes Texture NPOT support: yes Virtual Machine: no Direct rendering: true Reproducible: Always
Created attachment 90013 [details] Output from KWin. Here is some output from KWin running from konsole when I was trying to enable/disable compositing.
Run "qdbus org.kde.KWin /KWin supportInformation" and attach the output. If there's a line that says: Current Plugin: aurorae ply retry with the oxygend decoration.
Created attachment 90015 [details] Requested KWin info. I do not use aurorae, I'm using default breeze decoration.
> Compositing is not active Please try: sleep 15; qdbus org.kde.KWin /KWin supportInformation and after calling that (ie. while "sleep" sleeps) activate compositing (press SHIFT+Alt+F12), wait half a minute and then suspend the compositor again (same shortcut)

Yep, it happens also with a singlescreen setup.

I'm still experiencing this issue, but it happens randomly. It freezes only sometimes and I have to restart compositing to refresh the screen and make it work again.
Do you have glxinfo | grep sync_object In case, try: KWIN_EXPLICIT_SYNC=0 kwin_x11 --replace &
(In reply to Thomas Lübking from comment #10) > Do you have > glxinfo | grep sync_object No. > In case, try: > KWIN_EXPLICIT_SYNC=0 kwin_x11 --replace & Ok, I'm going to try that and will let you know.
(In reply to Jan Grulich from comment #11) > Ok, I'm going to try that and will let you know. shouldn't make any difference. could be https://bugs.freedesktop.org/show_bug.cgi?id=81551 ? LIBGL_DRI3_DISABLE=1 kwin_x11 -- replace &
Did you try comment #12?
Can you reproduce this bug after updates?
