Comment 27 for bug 144216

Ok, my system is up to date with nvidia 169.12 and latest compiz (0.7.2 updated today) and i am using both ff3.0b3 from repo as 3.0b4 downloaded from mozilla ftp.

It seems that the problem is still here. FF switch seems to be as fast as without compiz active but the resource monitor speaks clearly: during the switch the CPU is used at 100% if compiz is enabled, while usage is significantly lower without compiz (around 30%).

This does not seem to be a ff problem, also eclipse (3.3 and 3.4m5) tab switch suffers the same problem.

Also, FF windows resize animation is really slow.
