Yep, I've seen that as well. Someone with a decent scope should figure out
what's actually generated for hsync, and if that signal itself has some
sort of jitter. Maybe the hsync just isn't phase locked to the display
clock because of a different config for the VGA out controller.
LCD and VGA hang off different timing generation circuits I believe.
