not too sure if this is off topic (if it is i apologize) but it also happens when the pop-up track notifications are displayed in amarok. this might help figure out why the box remains as it might shed more light on the possible reasons.
if you go from windowed to full screen while the track change pop-up is active, it will not leave a black box. it leaves the black box only if the pop-up was issued while the video was already full screen. totem 2.18.1 xine-lib1.1.4 ubuntu feisty cheers! -- Black box after changing volume when playing video fullscreen https://bugs.launchpad.net/bugs/75600 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a bug assignee. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
