This is also what I would expect. But Apparently, displaying a lot of nodes outside the window slow the whole thing down. I get this profiling: http://bergel.eu/Picture1.png For this window being displayed: http://bergel.eu/Picture2.png I think I will try to the display boxes that I am sure they are contained in the visible part of the window. The polymorph extension seem to ease this.
