[SLUG] Video Glitch with Debian Unstable

[Heracles <heracles@xxxxxxxxxxxxx>]

I have recently been fighting with a strange glitch in my video display. 
I have an i740 agp card with 8Mb RAM on my work machine. It runs Debian 
Unstable (Originally Morphix) and when I upgrade I get everything 
working fine EXCEPT when X is running and I close a window the square 
around the mouse (a PS/2 Scroll mouse) remains on the screen until it is 
completely refreshed by moving another window over it. Just moving to 
another one of the four virtual screens I run does not help.

If I reinstall the original Morphix The problem disappears until I 
update again.  I wouldn't bother updating except that I need the 
functionality of a couple of the programs.

Any Ideas or is it a glitch in the i740 driver?

Stay well and happy
