Mouse-Positioning problem with Dual-Head

Binary package hint: xorg-driver-fglrx

The current ATI driver 8.28.8 has a serious problem with mouse pointer positioning when using Dual-Head (Big desktop mode) with different screen resolutions on the two heads.

See here:

If you don't want to frustrate dual-head users in the next release then I recommend sticking to ATI driver 8.27.10 until this bug is solved. 8.27.10 has a similiar problem (http://ati.cchtml.com/show_bug.cgi?id=210) but this only results in a visual glitch instead of a mouse pointer positioning problem. The visual glitch is nerving but it's ok to work with it. But the mouse pointer positioning problem is a real problem because it can lead to clicking the wrong buttons and therefor deleting the wrong files or stuff like that. I tried to work with it some time, it's impossible.

Maybe Ubuntu has the power to convince ATI that testing their drivers in some common Dual-Head configurations would quite be nice? It's really a shame: Each new version fixes something but also often breaks something else...
