Hi, After a deep discussion last night I've pushed an experiment patch to master that should improve painting performance a bit (not a huge amount, but still useful). However, I really need to know whether it causes regressions. So, if you're using git master, please update and report on issues when painting, especially with low opacity strokes and undo/redo or other brushes than the pixel brush. Issues can only appear when painting in wash mode, not build-up mode. Thanks!
