http://bugzilla.opensuse.org/show_bug.cgi?id=1210271 http://bugzilla.opensuse.org/show_bug.cgi?id=1210271#c5 --- Comment #5 from Paul Dufresne <dufresnep@zoho.com> --- Because https://bugzilla.opensuse.org/show_bug.cgi?id=1210271#attach_866231 had NVC0EXAPrepareComposite in the stacktrace, I now use: localhost:~ # cat /etc/X11/xorg.conf.d/12-driver.conf Section "Device" Identifier "paulDriver" Driver "nouveau" Option "AccelMethod" "exa" Option "EXANoComposite" "Yes" EndSection localhost:~ # And this seems to avoid this particular bug... but still having similar bugs. Up to now, I commented on: https://gitlab.freedesktop.org/xorg/driver/xf86-video-nouveau/-/issues/339 But I might try to reproduce it again, now that I have more debug symbols installed, and open an issue particularly about: NVC0EXAPrepareComposite -- You are receiving this mail because: You are the assignee for the bug.
