Public bug reported:
Binary package hint: xserver-xorg-video-radeon
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.
I have no screenshot, because this is diffcult to reproduce, and I
wouldn't know how to take a screenshot of the (HW-accelerated) cursor if
it had happened.
Xorg driver in use is xserver-xorg-video-radon 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.
I will attach the following:
* Kernel log (dmesg)
* Output of 'lspci -vvnn'
* Xorg.0.log
* xorg.conf
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.
