ATI Catalyst 9.x display corruption  

I have an issue with Aero and Wallpapers when using the Ati Catalyst drivers from this year (all the 9.x version I tried). I have attached the screenshot of what happens to the desktop wallpaper.

Has anyone else seen this issue?

It only happens if you apply a theme that has multiple wallpapers that can change. If you use a theme that has only one background it doesn't happen. I have an ATI HD 2600 Pro AGP card.

I am currently using the Catalyst 9.9 driver. I also notice that the text in the top title bar of windows occasionally gets scrambled so that you can't read it.

One other item I have found, is that the built in HD 2600 Pro AGP driver labelled Microsoft Production WDM 1.1 makes the Fan on the card run constantly had top speed. Where as the ATI Catalyst driver doesn't have this bug, the fan runs on low speed unless the GPU is under high stress.

My thoughts is that possibly its to do with texture caching? I assume the Aero interface is using 3D mode of the card and that the multiple wallpapers are somehow using more of the card memory. Just an idea. Anyone know if this is a common bug and if there is a fix?

The Catalyst 8.12 driver doesn't have this issue, but its a lot slower then the 9.9 driver.

ATI Catalyst 9.2 doesn't have this bug, but from 9.3 or later it happens. Someone in the AMD forum believes its a change with how Aero support is implemented in 9.3 and later.

The bug seems to affect both HD 2xxx and HD 3xxx AGP cards.

Here is my thread on the AMD site

Someone gave me an Intel 865 chipset motherboard and the problem is fixed.

Its an incompatibility between either the drivers for the Sis motherboard (mine was an 648 chipset) and the AGP port or between the ATI driver and this.

Intel chipset works perfectly.

Hi. Install the latest Win7 WDDM 1.1 driver and your problems will go away, with better performance.

Install AGP Drivers for HD 3850, 3650, 2400 PRO

Post the hardware id strings for your card there and I'll make an .inf for you.

Right click on card. Properties. Details tab. Change dropdown to hardware ids. Copy and paste results.

Glad to hear it's fixed with new motherboard though. Do the above if you ever need help with the original.
