I don't see any video but a transparent window

[Herfen]

Binary package hint: kdemultimedia

I only see a window with mydesktop wallpaper showing through instead of my video. I can hear the sound but can see any video using Dragon media player. Installing VLC doesn't cleared that issue cause of VLC already broke up after starting a file.

Can you confirm whether this is still an issue in natty?

If you don't mind, it would be very helpful if you could update the bug
report in launchpad to 'Fix Released' if it is no longer an issue for
you, or if it is still occurring under natty, please tag the bug 'natty'
so it's easier for us to track.
