I report the same issue as mentioned at the beginning of the thread - to me it looks like if the double buffering (in openGL) was disabled in code, and background would be redrawn on-screen while being updated.
I'm an indie game coder too, just without any stunning achievements

My conf:
Centrino 1.8, Radeon Mobile 9700 128 (M11), 1.5 GB RAM.
I double-checked on OEM and most recent drivers.
