Slow Randr rotation performance with r300 and XAA

[zK]

Binary package hint: xserver-xorg-video-ati

Hi,

I'm using Ubuntu karmic 9.10, when using xrandr to rotate screen on my Dell Latitude XT tablet and XAA i get very slow performance, much like incorrect refresh rates or something like that.

Drawing windows is very slow and major tearing occurs on the screen.

When using EXA as acceleration method the rotation works fine but i get rendering corruption in firefox.
