Looks like I had a graphics driver problem. Originally, I didn't think
that was the problem because the computer I'm working on has dual
graphics and it was crashing in Intel graphics mode and AMD graphics
mode. As it turns out, my dual graphics was broken and running Intel
graphics the whole time.

Now that's fixed and both drivers are broken, but at least they're
broken in different ways :P Sorry for the false alarm.

P.S. Buy NVidia graphics.
