Windows 7: Win7 basic graphical tearing,Acer Aspire One Netbook/Intel 3600 series

Hi,
on my netbook
Acer Aspire One D270, with
Intel Graphics Media Accelerator 3600 series
adapter thingy,
I am experiencing some graphical tearing when starting up any graphical app (media players, flash plugins).



The screen shears horizontally for about half a second when I open an application.

Any ideas why this is?

It doesn't always happen, but I believe it happens always after a resume (from hibernation).

Rebooting seems to solve the issue temporarily.

Is there any more info I can give to help with diagnosis?
Drivers are up to date.

[edit: Sorry, it's Windows 7 Starter, x86_32]

But there's no solution for my model I think]
