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. Additional info:
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.
