Being a BeOS user (a purely desktop system) and because I code under Linux, I see
XFree86 (v4.1 on my machine) as a user and as a developper. And this is where the problem lies. My Gnome or KDE desktops are slow in comparison with other operating systems, but XFree86, the 'engine' behind these desktops, proves me that it's not. Let's look at what I have in front of me: a dual Pentium III at 933Mhz with 512MB of memory, a Radeon 32 AIW, a modified Mandrake 8.0 powered by kernel 2.4.18.
gybe: OK so why MacOS X has the same problem than Linux + XFree : "it's damn slow".
Blame Aqua, not Quartz
Aqua is ridden with eye candy, useless eye candy.
Besides, Bascule, I can't see your problems on my machine (using Intel 3D, BTW), using IE (couldn't find the other app on the Net), doesn't have this problem. I had the same problem as Eugenia on the Mozilla issue, but if weren't for her, I wouldn't have realize it (it is so fast, you need to use the Print Screen button to see it).
