Resizing mozilla tests your window manager and mozilla's rendering
more than GTK+ itself. However, since you're seeing differences between
drivers, you might want to look at raw throughput to the card. Compare
the output of this command (let it run to completion, bonus points: run
without a window manager and let it be the only client):
x11perf -shmput500
On a 24-bit display, you should see numbers over 200. If not, it may
be a bug with your kernel with DMA transfers (which would be used more
by the proprietary drivers than the open source ones).
