You are probably using bob-deinterlacing, with many display devices
it causes a shimmer in the OSD. Try one of the other deinterlacers
if the shimmer bothers you. I've long wanted to fix this artifact,
which is possible, but it's never been high enough on my priority
list that it actually gets done.
