Description Veit Wahlich 2003-03-04 07:27:05 EST
Description of problem:
(Note: I use a 2 screen Xinerama system)
Using a TV card (with XawTV, Zapping and MoTV) something (I suppose Metacity as
it works fine using sawfish) begins to re-draw the whole screen at the moment
some window towers into the overlaying area. In grabbing mode this works just
fine - but is unusable as it eats up all CPU power...
This does not always happen, sometimes (for a whole Gnome session) it works very
well as used from using sawfish.


Version-Release number of selected component (if applicable):
2.4.34-1

How reproducible:
Sometimes

Steps to Reproduce:
1. Have an v4l overlay area on the screen.
2. Move some window to overlay the overlay area.
3. Screen flashes.
4. Try to work in the window that towers into the overlay area.
5. Screen flashes at every change of the window content.
6. If it works fine, restart Gnome/System.
    

Actual Results:  Nerving screen flashes.

Expected Results:  Non-nerving behavior.

Really has to be an X issue I would think, though doubtless there's some window
manager interaction. Perhaps related to Xcursor or something.

What video card are you using?  Please attach your X server log file, config
file and /var/log/messages file.
