Forwarding this EXA bug from a Ubuntu tester:

[Problem]
Corruption in application-specific mouse cursors under Compiz when EXA is enabled.

[Original Report]
I observe an occasional tiny corruption of the mouse-cursor. It manifests itself as horizontal garbage at the bottom of the "cursor square" (that thing around the actual cursor graphics which is usually transparent :) ). It only seems to affect certain applications which change the cursor. For instance, running Firefox remotely with X-forwarding on a RHEL5 installation, the corruption can appear. The cursor is different in this app compared to the default Ubuntu-cursor (because the app is not running on Ubuntu). I've also seen it in Emacs running locally.

Xorg driver in use is xserver-xorg-video-radeon git20081003.f9826a56-0ubuntu2.
EXA-acceleration is enabled.
Ubuntu 8.10 (fully updated, installed from RC).
Compiz is enabled.
Default Ubuntu cursor theme.
Graphics card: ATI X1400 mobile radeon (R500), 128MB RAM.

If more information is needed, please say so. I am also willing and able to test new GIT-snapshots of the radeon driver, and provide feedback if problems are fixed, etc.
