Is the effect a beat that it has roughly the frequency of your Notebooks screen refresh rate (60Hz)? (in german: Schwebung) > The effect is so nice that I thought about youtube ;-). Thinkpad > x60.. question is, how to debug it? No idea... check where the register of the HW cursor blink rate gets written?
