Created attachment 89014 [details] crash report Kwin always crashes when changing settings under Desktop Effects. Mainly when swithcing from OpenGL 2.0 to OpenGL 3.1 Moreover, there are times that moving any window is quite slow On the other hand, after a reboot -> problem is solved But this happens radomly.

(check glxinfo or lspci)

Yes, is 7th gen Try "grep -i" - it's uppercase (but i'm lazy on the phone "keyboard" ;-) Also of course after such crash and before a reboot.
Still no output from dmesg| grep -i gpu Now switching from OpenGL2.0 to OpenGL3.1 there was no crash, But after rebooting moving a window is slower with ghosting and frame rate drop. As you said, seems that's a graphics driver problem. But the graphics card my laptop has is the: Intel® Integrated HD 4400 Graphics and I have already installed xorg-x11-drv-intel.x86_64 Any ideas how I'm gonna solve this?
Do you also have trouble with GL 2.1? (GL 3.1 gets you no additional features - could be faster ... if not broken ;-) Right now there's little you could do otherwise (except trying a different MESA version) Fedora/RH bug: https://bugzilla.redhat.com/show_bug.cgi?id=1026530 (apparently reported before: https://bugzilla.redhat.com/show_bug.cgi?id=889726 ) Likely upstream bug: https://bugs.freedesktop.org/show_bug.cgi?id=53055 (Though they're probably all caused by a hung GPU)
Thanks for the message. Actually switching from OpenGL (any version) to XRender as composition type seems to work!! and also have all the nice effects (... almost as some of them require OpenGL) Should I wait for a new mesa? or stay with Xrender as default option?
If OpenGL compositing (actually any GL - this bug apparently hits chromium, openbox, ... as well) doesn't work atm., XRender is certainly a viable option (as you figured, some effects don't work since XRender eg. doesn't have the concept of a frustum) there are no known XRender specific issues. For less speculation on th nature of the issue (the fdo bug is actually on MESA 8.04), can you please record the output of qdbus org.kde.KWin /KWin supportInformation (with enabled GL compositing!) and ideally install a debug version for mesa & intel-dri (so that you receive a backtrace with line numbers)?

(In reply to Thomas Lübking from comment #8) > *** Bug 343307 has been marked as a duplicate of this bug. *** Comment #5 over there suggests potential relation to a resolution or dpi change during login: "By the way before KWin is crashing I can predict the crash, because the mouse cursor become smaller when KSplash has appeared (comparing to the Logon screen)."
Bug #343307 revealed glamor acceleration as culprit. You may want to check grep -i glamor /var/log/Xorg.0.log and if you are using glamor, revert to sna by adding ------- /etc/X11/xorg.conf.d/20-intel.conf ---------- Section "Device" Identifier "Intel Graphics" Driver "intel" Option "AccelMethod" "sna" EndSection -----------------------------------------------------------------
