Public bug reported: What was expected: -smooth transition to the window overwies when clicking a launcher icon with more than one window open, or when using the super+w shortcut to show all windows on the workspace.
What happened instead: -there was considerable lag when displaying the windows: stuttering and stalling occurred. Possible causes: 1) the fade in/out of other visible windows when opening the overview (only applies to clicking launcher icon); 2) the new "close window/window title" addon is initializing at the wrong time/place, causing unnecessary gpu/cpu load. This issue was not present in Precise, ie before the new close button plugin, but I now experience it in Quantal One of the most common occurrances is that the windows pause halfway through the animation for about 1/8 of a second before continuing the animation. Another is that the launcher click to spread windows animation pauses about 1/4 of the way through for about 1/8 of a second before continuing. While the animation is lagging I can see the partly-faded windows in the background. If I new where/how to start I'd look at the code for the new window title/close button plugin and try to figure out why it might be causing lag. I'm not entirely sure, but I think that it may be being called too early.
