I was watching a movie using mplayer.
At some point the whole screen froze.
However, the audio was still working.
I could switch to the text console and
kill mplayer from there. When I switched
back it was normal.
I also saw following messages in dmesg:

[80349.833880] [drm] stuck on render ring
[80349.833881] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[80349.833882] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[80349.833882] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[80349.833882] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[80349.833882] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
