Can you run 'unity --reset' and restore all unity settings and then try if the issue happens, It could be due to some non-standard settings in ccsm. when reporting graphical issues like this please always use 'ubuntu-bug unity' command so that the bug report is more helpful. for now 'apport-collect 886120' will indeed be helpful.
