           Summary: [drm] GPU HANG ecode 3:0:0x02fbf842 in Xorg
           Product: DRI
           Version: XOrg git
          Hardware: x86-64 (AMD64)
                OS: All
            Status: NEW
          Severity: major
          Priority: medium
         Component: DRM/Intel

/sys/class/drm/card0/error

The desktop blanks with black, then it is covered with horizontal lines and
bars.
If I refresh desktop /windows it shows some parts normal and others corrupted.
My feeling - It appears more frequently when I use some memory/cpu intense
applications like browsers with animation or eclipse IDE.
Screenshot attached.
