Created attachment 368736 brush icon problem after diameter 64 px
-
The parametric brushes don't are shown correctly, see Fig. 1. When the size is larger of 64 pixels the preview icon is appearing the same.
-
The radius of round brush is not calculated correctly. If you use a radius equal to 4 pixels, e.g., the final diameter is 9 px instead of 8 px. Is probable that the number of the spikes is interfering in this calculus, but if you use the minimal, I suppose for the round (2), the calculus would be calculated correctly (instead is not).
