Bug Description
I'm using Unity team release PPA. I am using the NVidia binary blob, GLXGears gets a steady 55 fps.
All aspects of the Unity desktop are slow. Switching virtual desktops is laggy. Alt-tabbing is slow, a quick tap may take half a second or so to actually change windows. Dragging windows is fast, but if they go near the edges and the maximisation effect comes up, everything slows down massively.
Sometimes the operations above are just slow, sometimes they become slideshows. There is no pattern that I can see for this.
Tapping super to bring up the dash takes forever. Tapping alt to bring up the HUD is relatively fast at first, but then it does the "gray out the Dash" animation which takes seconds.
Bringing up Dash previews is the slowest operation of them all. The animation shows maybe five frames total.
It is also extremely easy to crash Compiz. I usually have four windows open, one on each virtual desktop. This is relatively stable. Opening a fifth window is almost guaranteed to crash Compiz. When there are five or more windows open, regular operations such as switching virtual desktops or alt-tabbing crash Compiz. Bringing up the HUD or Dash crashes compiz every now and then. The crash reporter does not see these crashes, so I can't send them to LP.
