            Bug ID: 80613
          Assignee: chris at chris-wilson.co.uk
           Summary: xf86-video-intel with dri3 breaks kwin and plasma
        QA Contact: intel-gfx-bugs at lists.freedesktop.org
          Severity: normal
    Classification: Unclassified
                OS: All
          Reporter: eugene.shalygin+bugzilla.FDO at gmail.com
          Hardware: Other
            Status: NEW
           Version: unspecified
         Component: Driver/intel
           Product: xorg

When dri3 is enabled, kwin, plasma, and kde screenlocker hang sometimes after
screen lock and always after resume. I'm not sure, but have an impression that
in case of resume they hang for a time spent in suspended state. At least if I
suspend and resume in a few seconds, screenlocker and kwin unfreeze after
approximately same amount of time. Manually invoked screen lock does not hang.
If kwin and plasma are relaunched, new instances run normally.

I did not find anything special in logs.
