Windows stretched, mouse scaling differently

[Don Geddis]

I encountered the same symptoms, with the same workaround as:
https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1382462

My dual monitor setup became essentially non-functional, after installing ccsm. (Although I didn't make the connection until seeing this other bug report, many days later.) Disabling the "Detect Outputs" option (buried deep) in ccsm, restored my display functionality.

This is a very, very difficult bug for an end user to diagnose and repair.

P.S. I filed this duplicate bug report, because Christopher M. Penalver (penalvch) requested that many people who were reporting similar behavior at the original bug, all file their own copies of the same bug. So now I have followed penalvch's request as well.
