Title:
  Intel GPU crash corrupts fonts

Status in xserver-xorg-video-intel package in Ubuntu:
  Expired

Bug description:
  The bug occurs regularly, without any special action. I'm just working
  in gnome-terminal und using Firefox.

  Symptoms:
  * While working, the system suddenly freezes for a few seconds (like a typical crash in the X system)
  * Then I can continue work, but with corrupted fonts and views
  * New windows are sometimes readable again

  Don't know if the package is correct. Dmesg shows:

  [ 3647.214489] [drm] stuck on render ring
  [ 3647.214499] [drm] GPU crash dump saved to /sys/class/drm/card0/error
  [ 3647.214500] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
  [ 3647.214501] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
  [ 3647.214502] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
  [ 3647.214502] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
