Just draw a thick line and see if you can reproduce this http://people.apache.org/~rgb-es/Draw-341vs400.png
On the left, 3.4.1, on the right, 4.0. As you can see, handlers are misplaced on 4.0. There is also a lot of "noise" when you move an object around con 4.0 http://people.apache.org/~rgb-es/Draw-400noise.png This problem is absent on 3.4.1. I'm testing the 64 bits Linux build.

I cannot find any related issue in bugzilla. One user on ES forums reported that boxes like font name/size are not repainting for him, but I cannot reproduce that. Regards Ricardo
