I'm investigating bug lp:850992 (very hard to track down), and I notice
something odd. Each time I group or ungroup two objects, the render code on DrawingItem is called many times.
I want to know if this is expected and typical behavior since we could be
wasting lots of resources re-rendering the same item ever time we click on it or move it.
This is from /One/ group action. your thoughts?
Hi, set a breakpoint on DrawingItem::render and then press the group button. You can see how the dotted borders and those arrows around the selected items disappear in several steps and then are redrawn. Can it be that this has got to do with parallelization?
