Display corruption when launching compiz

Screenshot taken using 'gnome-screenshot --display=:1' on a vt and then switching to the Xgl session and hitting enter

I followed the steps in the wiki on a Compaq Evo N1000C (ati 7500 mobile), and got the same graphical corruption. The corruption disapeared when the desktop had finished loading though. when using synaptic the same corruption woudl appear over the icons and text.
i seem to have messed up my setup trying to fix it, so no screenshots im afraid. :/.
I will look into trying to reproduce it later (could it be related to the ati driver bug?)
kk

I had quite similar distorted screen on my Athlon X2 3800+ and Sapphire X600 Pro VIVO 256 MB (VEN:1002 DEV:5B62
RV370 primary, VEN:1002 DEV:5B72 RV380 secondary, PCI-E card nonAGP).

Is anyone still using compiz who can confirm this is still a problem?

Thank you for your bug report. As generic compiz as now been uploaded to Feisty (compiz-quinn is now known as beryl), we need to see if your bug is still present. If you can test the version of compiz in feisty (1:0.3.3-0ubuntu2~git2006112 or later) and tell us if you bug still exists, please do. Please make certain you are using Ubuntu's Xorg as well. We also require the make of your video card, to help debug driver issues. If you are using a newer ATI card (x1000 series or newer), please indicate so. To get this information, please attach /var/log/Xorg.0.log

Closing, due to lack of new information. If anybody can confirm this with a new compiz (0.3.6 or newer), please reopen the bug.

I'm running Feisty from Sunday's (4/15) daily build with all updates on a ThinkPad r40 with ATI 7500 Mobility. No additional packages have been installed. I am having partial display corruption issues when enabling "desktop effects". It only seems to affect the right 1/4 of the screen, I have attached a screenshot. If I restart the system and log back in there are additional issues where I do not see anything on the panels and they are still both cut off in the same spot as the screenshot. I can still right click the panels and get context menus. Let me know if you need anymore information or if I should have additional packages installed that would fix this. Changing my theme has no affect. If I choose to click on "use previous settings" when first enabling desktop effects the right 1/4 of my panels are still cut off unless I move them to refresh them.

I can reproduce at will in gutsy, reopening.
I use the radeon driver, my card is a Radeon Mobility 7500, with only 32MB RAM. I suspect this has something to do with it, as in the standard resolution of my laptop (1400x1050) I see this kind of corruption. Maybe the textures are too big to fit in video RAM? If I set the resolution to 1024x768 (in xorg.conf), I am able to use compiz without corruption.

If I reduce the depth from 24 to 16 bpp, I'm able to use compiz with 1400x1050. This confirms my memory limit hypothesis I think.

Still not a bug, it's simply a limitation in your hardware.
