Public bug reported: Here is an example image : https://imgur.com/J4xZht3
I've had this issue for years, and I really want to see it fixed, as it is a regression that came a long time ago. It didn't do this when I started using compiz (yearssss ago), but it does it every time now.

When I cltr+alt+click to rotate the cube, the edges of the monitors draw farther than they should. So this makes the "cube" look really messed up.
