Version:           unknown (using 4.3.95 (KDE 4.3.95 (KDE 4.4 RC2)), Kubuntu packages)

OS:                Linux (i686) release 2.6.31-19-generic

All fullscreen flash videos (say youtube.com) from all webbrowsers are "de-fullscreened" by kmix osd (plasma?). 

Assign kmix's volume up/down mute shortcut keys (better if we have multimedia keyboard)

How to reproduce:
1. enable multimedia keyboard layout or assign kmix vol up/down shortcut keys
2. play a video in flash, say here http://www.gurumaa.com/videos/duality-of-mind.html,
3. click play and click the [x] fullscreen
4. press any of the assigned shortcut keys for kmix osd (multimedia volume up or down or mute key); say press volume up shortcut key
5. we can observe here that the video is no-longer fullscreen.

Expected behavior:
1. play a video using any multimedia player (smplayer, vlc, dragon player, mplayer-gui)
2. use multimedia keys (assigned kmix shortcut keys)to increase or decrease or mute the volume
3. the fullscreen window stays fullscreen.
4. this is the expected behavior.

thanks.
