I recently installed Windows 7 on my laptop and got some display problem. After using the computer for a while (e.g. 10 min), the edges of the windows break. Here is a screenshot; open it in a new window to see more clearly:
The broken pixels stay even if I minimize/maximize/move the windows. The problem can be temporarily solved by turning off Windows Aero and then turning it on; however the problem re-appears after a while.
Sometimes the interior of the window also breaks, but this happens less frequently.
It's a Dell Latitude E4200 with Intel Graphics Media Accelerator 4500MHD, running Windows 7 Ultimate 32-bit. According to GPU-Z, the GPU is a 65nm GM45 running at 475MHz.
These are the drivers I've tried:
- The one that was installed by default
- The one from Dell's website (22.214.171.1245)
- The latest one from Intel's website (126.96.36.1996)
The version numbers are copied from their websites; I don't know why they use two versioning schemes. And I'm pretty sure that I downloaded the right drivers (Win7 32-bit).
This never happens on Windows XP and Windows Vista (yes, right now it's a triple boot system). Has anybody seen this before? Any idea how to solve it? I'm using Vista happily but I do want to be able to use 7 too!
