Sorry if this has already been asked, but I can't understand and solve this problem (actually, I don't know if it's really a problem):
when I open a video file, it produces a strange effect, a sort of "transparency", if I minimize the VLC window, it distorts the other windows; if I uncheck "overlay", the effect disappears, but then if a play a video full screen, VLC doesn't play it not fluid anymore.
By the way, what is overlay?
Thanks for your help!
