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

Defer initial modeset until the first BlockHandler invocation
This ensures that the screen pixmap contents have been initialized when
the initial modes are set.
