I have an ATI Mobility Radeon HD 4550 using the lastest catalyst driver.
Gnome-shell works but the panel colors are wrong and I get artifacts when it compositing effects are being done.
any ideas?

Open up System Info and see what it says about your graphics card. That's what it looked like to me when I tried using catalyst, they failed or something and it defaulted to vesa drivers. Try using the open source drivers, that's what ended up working for me.

I also have the exact same problem. Running the open source drivers work pretty well. Gnome 3 runs like a dream, however, games do not.
(Yes I installed the library for compressed texture support or whatever it is support and enabled it, and un vsynced my desktop.)
So... I have to decide, graphical artifacts and flickering in my desktop or slow / broken games.
The odd thing is the answer "use free drivers" is the only answer I can find to this problem... Is anyone working on fixing this?

I'm using gnome 3 from testing repo with no problems at all on an eeepc. I suppose the culprit of this behaviour could be a sort of incompatibility with the radeon driver.
However, any ideas? Did anyone else find the same problem before?

Same problem here too. In system info for graphics stays "VESA: RV770". It's totally unusable this way, so I'm waiting at Fallback mode till better times with fglrx The only answer I found so far is the same as @cybercyst typed. There was an easy way for changing from catalyst to open-source driver with a simple script that renames/restores xorg.conf, but it takes a restart every time you need to switch. Which is almost the same as rebooting to differently configured installation.

Same problem here using Radeon HD 4670.

Moved to Applications & Desktop Environments and merged...

There is something really interesting. Try to turn the display in any other direction than normal like anti-clockwise or 180 degree. The image corruption can be seen only on the main toolbar and using the activities button doesn't corrupt the display like in "normal" display orientation.

This is interesting, it also works that way with my card.
But I think it will still take some weeks until we get a working Gnome3 / catalyst combination. Until then, I use Gnome3 Fallback + Compiz

I'm using the xf86-video-ati driver with my Catalyst and all seems to be working well in GNOME 3. By all means, I'm not playing games on it, but I don't have artifacts nor do I have colors being off. ^_^
Cheers.
