Comment 19 for bug 1060782

So reading the comments above I ran some tests:
- running nvidia-current 304.51 glxgears +- 60 fps intermediate or maximized;
  With Unity, toggling any window size from very small to maximized is instantaneous, minimizing is instantaneous, but leaves behind a brief outline of the window as it shrinks, I never noticed that before; if hidden Unity doesn't come back out unless you press the Super key, but there is a bug report on this issue;
- running nouveau without Unity (unchecked in ccsm) glxgears +-255 fps intermediate +- 41 maximized;
  "Sans" Unity, toggling any window size from very small to maximized is instantaneous, minimizing is somehow slow;
- running nouveau 1.0.2-0ubuntu3 glxgears +-255 fps intermediate +- 41 maximized;
  With Unity, toggling any window size from very small to maximized is instantaneous, minimizing is extremely slow; when hiding Unity leave a shadow behind that doesn't get filled in.

The video card is a GeForce GT 520.
