Bug Description
See question #195487, which I think was wrongly assigned to xserver-
https:/
To rehash question #195487: I just upgraded from GNOME 2.32 on a PPA-loaded Maverick 10.10 to 12.04 using GNOME Classic No Effects.
Window updates are noticeably slower in apps like gnome term, pysolfc and nethack-x11, while some gtkperf tests are significantly slower on my machine than on my wife's slower machine.
I ran it under all of the Unity and GNOME variants and the times weren't significantly different.
This is a list of the significantly slower gtk operations (along with a couple of faster operations):

We both have the nvidia 295.40 driver installed.
She still runs a PPA-loaded Maverick system.
My system has an Athlon II X4 640 CPU with GeForce 210 GPU while she has a Phenom II X2 555 with 8400GS GPU. Does screen size matter?
The monitor, video card and binary driver are the same today as they were 48 hours ago (when I upgraded).
I get 3400fps in glxgears and Tux Racer responds well, so it's NOT bug #982485.
It was a clean install from the 64 bit Live DVD, so there's . (Since /home is on it's own partition, I'm able to upgrade w/o much worry.)
