I have just tried and the problem persists with that option. It seems like the
first couple of lines of pixels at the top of the screen are most affected. I
am not sure how I am going to explain this, but it also seems like that
specific area is impacted by whatever happens in the area below. For example I
have just noticed that if I move a window (by clicking on the title and not
releasing it, but moving it around), the area on top of the screen is directly
impacted (looks like there is a reduced mapping of the pixels between these 2
areas).


Thanks for your help :)(In reply to comment #16)

Thanks for your help, and let me know if you need more info/tests :)
