Summary0000237: ESC to cancel operation now takes very long
DescriptionThis is weird... Up till the last build, I specifically recall this taking a second or so at most. However now, if I rotate some brushes and then hit ESC to cancel the rotation before releasing the mouse, it takes around 8 seconds. DR is non-responsive during that time.

TagsNo tags attached.

This happens instantly on my end, I can't believe this takes any longer than a few milliseconds. What are your system specs?

1.4 MHz system - and this symptom is relatively new (last few builds). I use this function all the time, and only then did I notice something changed.

But I've narrowed it down to a dependance on map size (maybe). Open, and create a three-brush func_static like shown. Rotate that, and ESC-cancel the operation. For a map this size, I get a 2 second delay. On a small or empty map, I do get immediate results that you described.

To repeat though, I've always been using the same map for this test - in the last three or so drops, it's acting different.

Confirmed, I can notice it in, where even my system is lagging. I'll have to do some profiling in order to hunt this down, although I'm not sure I can do anything about it.

If I can recreate this on Linux I might be able to attack it with the debugger.

It should behave the same on linux. I suspect that the [b]revertTransform()[/b] calls might be misplaced and affecting the whole scenegraph. I'll have a quick look of how I did this.

Yep. That was it. I traversed the whole scenegraph with a revertTransform() call. I didn't suspect that this was so expensive. Anyway, it should be fixed now.

If traversing the scenegraph is very expensive, this is an important piece of information regarding the renderer because AFAIK the graph is traversed every frame.

Either that or the revertTransform() call that was applied to every visited "Transformable" instance.
