Interesting Graphics Issue.

Beta drivers are on, here goes nothing!

So far since boot, I've not had a problem. But it can crop up at anytime. I'm going to run a few apps, play a game for a little bit, see if that will upset it at all.

Will post back my findings.

It's safe to say that i upset it
While not as bad, its still there. Playing GoW; minimizing to desktop was fine. Quitting the game, cause the same corruption; yet not to windows, but to the taskbar instead, one i've not had before; and with the new beta, objects in GoW like to disappear when you get up close.

While it seems to have calmed the situation its still there. Disabling Areo stops the corruption completely. I think its a bug Microsoft may want to look into; else i cant fault the OS really. I do have the desktop refresh issue; like if you empty the Recycle Bin the bin still looks full, or if you move a file from desktop to Recycle Bin, its still on the desktop until you hit F5. But a reg tweak cured that one.

Will keep looking into this one, 'bout to try this on another box, which has a nVidia 7900 GT, see if i can't replicate the corruption with the same driver on another box.
Will post details

Well GoW worked flawlessly before the beta driver, so I would imagine that is all it is down to; its a beta so i don't expect perfection. I had a go at compatibility mode, it didn't really change from what i could tell. Textures still went walkies and the corruption on the taskbar remains. Funny how it has switched from window to taskbar; it is exactly the same kind of corruption as my previously posted screenshot. All in all, a rather odd bug. I'm not really a software guy, hardware is my speciality but even so doesn't hurt to give it a shot.

Thank you all for all of your help, I will post my findings on the other box, see how that makes out.

I've had a similar issue, except my whole screen is affected...
I'm eager to see what your 7900GT card does, as that's what card I'm running right now....

Hi guys,
Heres the results from my testing yesterday. First up, specs of the test rigs.

Test Rig One: (Intel based)
-Asus P5B-VM
-Intel E6600
-2GB DDR2 RAM
-Windows 7 Build 7100

Test Rig Two: (nVidia based)
-Asus Striker Extreme
-Intel Q9400
-2 GB DDR2 RAM
-Windows 7 Build 7100

I tested both 32bit and 64bit versions of the OS and Drivers.

The 7900GT performed flawlessly throughout 32bit testing in both rigs with both the 186.18 and the 190.38 beta driver. In 64bit; it was the 186.18 driver that caused video corruption, where as the 190 beta worked fine.

The GTX 280 performed consistently better with little or no video corruption in Test Rig Two than in rig one on both drivers under 32bit with the 186.18 driver. In 64bit the GTX280 worked fine with the 186.18 in test rig one, rig two showed video corruption. The 190 beta, in 64bit showed no corruption on both rigs.

Conclusion: If you're suffering from corruption, it may well be worth updating to the latest beta drivers on nVidia's website. It also seems that the 186.18 driver seems to have less problems under 32bit. The 190 beta seems to be the winner of 64bit.

Be sure to check out the new "Power management" option in the 190.38 drivers.You will see it in "manage 3d" control panel.It adjusts clock speeds depending on use.Best to set at "adaptive" or "performance"
The "Power management option" will only be present with newer cards.
