Have you seen anything like this before?
Not always but permanently shows up this strange behavior. What's the name of that problem? And how can I solve it?
I tried:
- driver update
- full driver/app uninstall and Lenovo ThingVantage System Update
- turning aero off (... and everything works fine)
- monitor driver update (but only generic PNP monitor found)
Configuration:
- Lenovo Thinkpad T400s (was Vista but clean Windows 7 install now) (update: this is not a lenovo specific error)
- Windows 7 Professional (ENG)
- Mobile Inter 45 Express (WDDM 1.1)
Update
I found the 'correct' name: visual corruption.
The problem appears when VT-d technology is enabled (ie. for VPC). Turn off and hopfully everything will work fine. Details: http://forums.lenovo.com/t5/Windows-7-Discussion/Bizarre-screen-artifacts-on-R400-Integrated-Graphics-running-Win/m-p/199594. In short: go to BIOS and disable it.
Update II
Just for google:) It's hard to characterize the problem so there are some keywords for it:
aero, glitches, pixel, bug, visual corruption, garbled textures, frame error, virtualization, vt-d

1@boj - my answer only pointed you in good direction, it doesn't actually answer the problem. You should write the answer yourself, with exactly what fixed it, and accept it (you can't accept your own answer before 2 days, though). It would make it probably more clear. Finally, my answer is only about heat, nothing really linked. – Gnoupi – 2010-04-02T12:54:20.757
