I've noticed some temporary visual junk at the right edge of the screen when the pointer gets updated. The best way a can describe it is that when the pointer changes you see a random "sprite" for one frame on the right edge of the screen. The random contents seem to stem from the framebuffer itself.

I see this most often in the following situations:

  - moving the pointer over a link list in firefox: the pointer changes constantly between "pointer" and "hand" symbol

  - moveing the pointer over the middle scrollbar in gtik: the pointer changes between "text", "pointer" and "left-right resize/move" symbol


I'm currently using commit

on a Lenovo T60 running Fedora 9 preview.

Could be the same problem as the "x1250 horizontal tearing problem" discussed on the mailing list. But I see this without a running video, just normal desktop usage.

Does turning off tiling help?

Option "Colortiling" "false"
Comment 3 Stefan Becker 2008-04-30 15:22:44 UTC 
Tried that:

$ fgrep Tiling /var/log/Xorg.0.log
(**) RADEON(0): Option "ColorTiling" "false"

Problem is still there.

Unfortunately no...

I haven't seen this in a long time. I think it disappeared when Alex did some changes to the PLL handling.
