Bug Description

Not sure if it's related to the others issues I already have with my nvidia card (proprietary driver), only when unity is activated (bug #687738 and since last week, bug #703140), but when I'm using scale from the launcher (not with the Super + W shortcut), all is really slow, taking almost 4-5 seconds to make the scale effect.

Here is a video where I first do Super + W to activate scale at a reasonable speed, then clicking on a launcher to trigger the same effect takes some seconds, making the screen freezing.
This is since unity 3.2.12, no issue before.

maybe related to the wrong behavior in bug #705459 if something is stalled in a call…

Jason found that the issue is related to the redecoration compiz call in unity which is expensive. The same issue if affecting alt + tab in compiz btw. (the more you have maximized window, that is to say, undecorated one, the more time you will spend).

unity (3.4.0-0ubuntu1) natty; urgency=low

  * New upstream release:

    - Fix performance issue due to redecorate windows (LP: #705427)
    - Change automaximize value to 75% of the workarea (LP: #708809)
    - The launcher should not let you dnd special icons (LP: #709119)

  * debian/control:
    - recommends again places now that unity can support them
