simulation

An screenchot does not reproduce the problem I am seeing because it mixes a lot
of video frames (and not just two) in the resulting image.

I have made up a picture showing the effect. The border between the frames is
not static but changes randomly and is usually placed at the top, between the
10% and 30% of the screen.

BTW, playing the same films I have tried using another computer with an Intel
card attached to the same monitor (same resolution) run smoothly.
