@Gabriel Loewen : You might be facing the problem due to latest mesa update : bugs 599741 and bug 616997 have similar issues.
Could you open a new bug using : ubuntu-bug xserver-xorg-video-<driver>
where <driver> would correspond to the graphics card your system has.
And then add a unity task. Or mention the bug# here..
