Window updates much slower under 12.04 than 10.10
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?
Is this a known upstream regression? What package should I file a bug under?
Can you help with this problem?
