It's getting me crazy!
compiz or unity refresh screen (like I run compiz --replace or unity --replace) by every movement I do (e.g ctrl+tab, super+w) and somehow unexpectedly! sometimes it failed to reload title bar and keyboard functions like ctrl+tab and alt+F2 stop working, and I had no chance but reboot!
Sometimes it work without any problem. I couldn't found any reason why this happen.
I wanted to report a bug but I don't have enough information about it.
decorate windowsparametere fromanyto(any) && !(class=covergloobus.py)because it windowed covergloobus (problem start when I changed it). I thought problem is caused by that, but I restart setting and having same problem – Behzadsh Jun 11 '11 at 16:20
