--- Comment #20 from Marcin Slusarz <marcin.slusarz at gmail.com> ---
It seems gnome-shell triggers some bug in our OpenGL driver, which causes the
hardware to raise errors (GPC1/PROP traps), which kernel fails to ack/cleanup
and eventually this leads to context switching failure.

If we'll fix the OpenGL driver, the other bugs won't matter (and they are much
harder to fix). So the first step is figuring out how to reproduce this bug in
a matter of minutes and generating an apitrace and/or mmt trace.
