Unfortunately it does not help. It is still so slow. Sebastian: I thought it was enabled by default because of the spec composite-by-default. Sorry. Upstream answered for a small period but now seems not interested anymore: they are sure that the poor performance is caused by the lack of RENDER ACCEL for this driver.
"The lack of RENDER acceleration is quite clearly the bottleneck for scrolling performance with most apps here. Again though, for EXA you'll definitely need the xserver exa-damagetrack branch, as otherwise EXA itself is incapable of accelerating a lot of things properly." We could try to open a new upstream bug, more specific than the one I opened. -- Very hi CPU usage when refreshing a window. radeon driver https://launchpad.net/bugs/73473 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
