Comment 8 for bug 299330

This bug/problem is of hard reproduction. I have two computers here, exactly the same specs, and one has a slow Alt+Tab window switching, and the other one has no problems in this operation. I did some tests with Compiz and the problem just don't seem to be with the desktop effects. I also disabled all the resources I could imagine to cause this problem, and no success.

Well, switching through opened windows it's being really painful for me, and I really hope that you guys can find out what's happening.
