Created attachment 18803 [details] Xorg.0.log I am running GNOME along with Compiz. When playing video using xv output, partially overlaying the video playback area with another window results in a blue (#0101fe) area where the overlayed windows dropshadow should be. If the overlayed window is transparent, the video area behind the overlayed window (that is visible due to transparency) is filled with the same blue colour. Any occurrence of this blue colour overlayed onto the video image is replace by the video image underneath it. Moving the video playing application around the screen, the video image remains static while the window is being dragged and the area around it is the aforementioned blue colour as long as it's within the confines of the window being dragged around the screen. As soon as I stop dragging the window the video area is moved to the correct screen region. Attempting to take a screenshot which includes the video playback area results in that area being replaced by the same blue colour.
I forgot to mention that this only applies to the first video that I play. Subsequent ones behave as expected.
Either your distribution has switched the order of the video outputs on you to prefer the overlay, or the video player is intentionally choosing the wrong port. The overlay can't be correctly supported with compositing, and the result is what you're seeing.
