Well, even if I knew how to fix this one, we still couldn't just remove/improve the already-in-use brushlib setting.

Hi Martin - I'm not sure if or how I should go about reproducing this one. If you have the time, would you be able to close this one out and reopen something on the github tracker showing the size dependency issue in greater detail? Many thanks.

New brushes show that this feature is actually still very useful, and the problem with the size-dependent CPU usage is not a big issue.

However the problem with the size dependency should be checked (it might even depend on the event rate of the input device).

Brushes using this feature (eg "hair") seem to be pretty resolution/size dependent, some sizes showing no jitter at all, and other more than expected.

Even worse, it is very easy to overload the CPU with this feature (just increase the brush radius of the "hair" brush), causing MyPaint to freeze for a long time (perceived as crash).
