Comment 145 for bug 38131

Same problem for me. It seems when firefox is running and I opening new tabs or I making some window-operating (minimize, maximize) the firefox and xorg eat my cpu for a sec. Cpu usage goes up to 90-95% and everything are stopped for a moment. It is not funny when music breaks like on old turntables Now I using opera and there is no problem. With 10 opened tabs i can do anything without extreme cpu usage.

System: Ubuntu 10.04 32bit
VGA: ATI Radeon HD 3650 (Catalyst 10.11)
Browser: Firefox 3.6.13

Some additional info: I changed my VGA in last few days and the previous card was an Nvidia Geforce 7600GS and this problem has started now. It may be some fglrx-firefox-xorg incompatibility or I was just lucky before vga-change?
