I think that's a bug in the XFree86 Server. I had this bug never with my
old ET4000 card on an ISA board but it happens with an S3 card on a PCI
mainboard.

Netscape heavily uses backing store on the server to be able to rapidly
redisplay loaded images (that's the reason your XServer-Process grabs so much
RAM when running Netscape) and to be able to scroll smoothly.
So it must be a bug with backing store and the XFree-Server.
