I wonder if the newer intel drivers in experimental (2.4.1, Lenny has 
2.3.2) would help things.  They don't seem to be easily installable, 
unfortunately.
Another thing to try would be the obsolete "real" i810 driver (the one in 
Debian is actually linked to the "intel" driver).

I haven't experienced any graphical glitches myself, mostly just very 
inadequate performance.
My experience with composite effects in short:
 - Using the default "EXA" AccelMethod: effects work fine, terrible 
performance, using XRender didn't seem to help
 - Using "XAA": perfect performance, but can't play any video, didn't try 
XRender
Since XAA is obsolete, I'd rather see EXA working than work around the XAA 
problems (I did find some poor workarounds for the video issue...).

I'm reverting to KDE 3 for now, composite effects were the main attraction 
for me and otherwise I'm still missing some functionality (khotkeys).
