System is a laptop with a HD3000 GPU (Intel Sandybridge i5-2520M) running Linux
4.7.3 with Mesa 12.0.3.
I have been playing a video in the mpv player and the moment I double clicked
on the screen to exit full screen mode of the player the display froze for a
couple of seconds. After that, the following error has been logged.
This exact same issue (GPU hang when switching between full screen/windowed
video playback in mpv) has happened before a couple of times already. The issue
has occurred with both Compton and the Xfce compositor running. This report is
with the Compton compositor running.

[146283.421666] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, incl
uding userspace.
[146283.421667] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI
-> DRM/Intel

component if it'
s not a kernel issue.
[146283.421668] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
