Many issues with xfce 4.2 rc1 & compositing

[Алексей Иванов]

Hi!

I have a problem with running mplayer under xfce 4.2 rc1 with 
compositing switched on. When I press "F" to bring picture into 
fullscreen it runs with many artifacts. The screen flickers. I see some 
black spots (one is located on screen exactly in place of XMMS main 
window even though it's being run on another virtual screen). And I very 
often have to press "F" for several times to make fullscreen picture 
visible (if I don't do several presses of "F" button I see only black 
screen :(( ). And I see the same even in windowed mode often.
Compositing generally seems to be ..err.. not good?. If I send some 
moving picture to the desktop (xwininfo and a click on desktop gives 
window-id (by the way, can it be done automatically without clicking?), 
then I use it with "mplayer -wid $window-id foo.avi" or 
"/usr/X11R6/lib/xscreensaver/blocktube -wireframe -window-id 0x1000003 
-visual GL") it makes flicker _everything_ - main bar, taskbar, all 
windows :(
What should I do?

Some (probably) usefull info.
I run fully installed Slackware 10.0 on PIII 800MHz, 256Mb RAM, noname 
Nvidia GeForce 4 MX 440.

Thank you for reading this stuff :) I hope it can be fixed without much 
pain :))
