Created attachment 119134 [details] dmesg output Hi all, I'm facing a huge performance drop with latest git version of xf86-video-ati. Creating and moving windows is very slow. There is also another problem where the mouse cursor is inaccurate positioned by some pixels when it is changed (input cursor, windows resize cursor, ...) This does not happen with the last released version 7.5.0. I bisected the driver and found the bad commit before that commit or when it is reverted both problems do not appear: 673e1c7637687c74fc9bdeeeffb7ace0d04b734f is the first bad commit commit 673e1c7637687c74fc9bdeeeffb7ace0d04b734f Author: Michel Dänzer <michel.daenzer@amd.com> Date: Thu Apr 2 17:54:33 2015 +0900 Defer initial modeset until the first BlockHandler invocation This ensures that the screen pixmap contents have been initialized when the initial modes are set.

Does this still happen with http://cgit.freedesktop.org/xorg/driver/xf86-video-ati/commit/?id=548e97b3b7d1e94075a54ca2bb4eb683025098a7 ? If yes, what desktop environment are you running?
No it is not fixed. The desktop environment is gtk2 based Mate 1.6.0
MATE 1.10.2 seems to work fine for me, not sure what's wrong on your end. :( Do you have compositing enabled in the MATE settings? Can you also attach the output of xrandr when the problem occurs, the patch you use for reverting the bisected commit, and the Xorg log file from running with that patch?

Created attachment 119243 [details] patch to revert commit 673e1c76.
