I have the same issue with firefox without compiz (AiGLX enable + radeon driver). The CPU goes to 80-90% but no slow refresh with the internet pages. With compiz (freedesktop) from repository or build by me i see slow scrolling of pages with firefox, nautilus, gedit and acrobat.
I think is a driver issue or a xorg problem... Bye, Luca -- Very hi CPU usage when refreshing a window. radeon driver https://launchpad.net/bugs/73473 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
