(Solved) Graphical glitches with ATI

[vivaelamor]

Hello, I have installed the Penumbra collection on my Arch64 system and am having trouble with all sorts of graphical glitches.

My system is an Intel Q6600 with an ATI HD4850. I am using ATI Catalyst 9.6 with xorg-server 1.6.1 on KDE 4.2.4 (desktop effects disabled).

The first I noticed was the barrels at the start of Overture disappearing depending on the angle of the view. The bed's frame and numerous other objects in the same room also have this problem.

I have also loaded Black Plague and noted similar problems with objects disappearing in the room at the start.

I have been through the forum and noted that there are similar reports from other ATI users and a possible hotfix for windows users.

I had tried fiddling with the settings (which i'd had all on high) but without switching them off one by one it just seemed to make things worse.

I have made sure that Catalyst AI is disabled in amdcccle.

I have attached a log from Overture.

Edit - Here is the output from ldd as well:
