I enabled showing window geometry to test my new site on lower resolutions by
resizing the firefox window. As I was resizing I held it down to a lower
resolution and adjusted to be exactly 800 or 640 which is why I held it longer
than people usually resize.

As I did that suddenly everything jumbled, black appeared then half a window,
everything completely jumbled up as if something just broke somewhere that
instant. It was operating quite smoothly and without artifacts until that
moment.

I had xrender enabled instead of opengl because that made resizing windows
faster, but after this incident I had to switch to opengl again and even then
there are some artifacts remaining, like in the panel. Here is the shot of
that: http://memenode.com/misc/reports/panel_jumble.png
