Re: Mplayer - vdpau - composite disabled screen flashing
Another thing for you to try: Can you run in windowed mode, where the problem doesn't happen, then position the window such that the top-left corner of the window (the client area, not the title bar etc) is exactly at the top left of the display. Then, resize the window larger and larger, until almost full-screen. I believe you'll find that at some size the problem will start occurring. Once that happens, try moving the window slightly to the right (but not changing the vertical position). Does the problem go away ever? If not, try moving it down slowly, keeping aligned to the left side of the screen.
