<pre>This is a weird one. I was playing the Talos Principle while hacking xboxdrv to
support the Steam Controller. While switching windows, it got into an odd state
and the whole display froze. I was able to ssh in from another machine and
issue a reboot but after losing contact, it didn't actually reboot. I hit the
power button.
When X came back up, it had weird red artifacts all over the place. It's hard
to describe so here's a screenshot.

I tried rebooting again. Same thing. I'm on Gentoo so I tried
upgrading/downgrading various things but nothing has made any difference. I was
then notified of a Gentoo forum thread where another user had encountered the
same thing following some kind of crash or freeze in QuDos (Quake 2). This is
his screenshot.

The only thing I upgraded since the previous reboot that could possibly be
related was LLVM from 3.9.0 to 3.9.1. I haven't downgraded that because it
takes ages to build and I doubt that is the cause.
I have fired up the Talos Principle again in the hope that it would knock
things back into the shape. The game looks fine but the desktop remains
unchanged.
I tried firing up Weston (which I don't normally use) and it didn't show the
same corruption when I launched Thunar. That may be a red herring. Excuse the
pun. :)
