When Gala animation is disabled (in dconf Editor) apps that are minimized to Plank cannot be restored or maximized in any way. Alt-Tab don't work, right click - maximize don't work, left click or double click also don't work. They can just be closed with the right button click on the Plank icon.
Personally I hate all those animations but from today (monday) I must use them or I cannot minimize and restore.
EDIT: One more thing. When closing the application with animation enabled the window does not "animate" properly. Instead I have an animation of new workplace sliding in every time I close any application, like I'm switching them.
EDIT 2: Sorry for this but I just realized something. I mention that one cannot restore a window minimized to Plank. It seems that Plank somehow react to restore in a way that it gets hidden although I cannot see the window. This is repeatable and when I minimize the invisible window again the Plank show it self. I'm using intelligent hide mode on Plank. So the Plank is reacting like everything is OK but I cannot see the window anymore once it gets minimized.
Thanx for your time and effort.

Yeah, we forgot to show the window on map when animations were disabled, fixed now. That animation of a workspace sliding always happens when you close the last window on a workspace. If that's not the case, it'd be great to see a screencast of it.
Thanks :)
