Running VLC (v.0.9.8a-1, Debian/experimental), video output XV, when pointing the mouse to open another window, the VLC window turns black.
It only happens with video output XV, not with X11.
It could be a VLC bug but when using openbox wm this bug doesn't occur, so it's
possibly a xfwm4 bug.
I am using the latest svn version of xfwm4.
It only happens with compositor enabled.
I checked this again and noticed openbox doesn't seem to use compositing, so it could be a VLC bug.
If you think it's not a xfwm4 bug I'll file a bug to VLC.
It's very unlikely a bug in xfwm4. A bit of googling shows that it happens with other composited window managers too. Try using another output method in vlc.
Please also note that the problem does not show with other media player such as MPlayer and I cannot reproduce the issue either using the vlc 0.9.8a with either nvidia proprietary driver or nouveau.
So what I'd suggest is:
1) Try another output method in vlc and see if the problem remains
2) Try with another media player (e.g MPlayer)
3) Try with another composited window manager (e.g. metacity with compositing on, compiz -although this one uses OpenGL and not xrender- or even xcompmgr)

Thanks, on my system too it doesn't happen with MPlayer or Xine.
Since you cannot reproduce the bug with the nvidia driver or nouveau, it points to xserver-xorg-video-intel (2.6.1-1) driver and VLC.

Not necessarily, it works also with intel here. Actually, I remember seeing that bug with older versions of vlc, but I fail to reproduce it with the latest version (that's on F10).
This is issue no longer happens
