Public bug reported:
Presumably Unity, or in general the user interface of Ubuntu 15.04
(Vivid) suffers severe performance drops. To be more precise, when my
system happens to be in this state, every animation, like moving
windows, opening menus (fading in/out), or opening the dash is very
choppy (I would guess 5 FPS, but I didn't perform proper measurements).
I could not find the triggering element, although I know that closing
some windows will solve the problem, after which I can reopen those
windows, and have normal frame rates. In Compiz Config Settings Manager,
I already set the refresh rate to the correct value of 60, and disabled
refresh rate detection. I believe that from the attached data it's clear
that I'm using the latest nvidia drivers provided by Ubuntu.
