Brush: Ink (included with download brush)
Today I've run in with a lot of (counting on four) sudden program closings within an hour and a half or so. Just... gone- the window just disappears as I'm working.
I've also been trying to get the presets to stay on a specific brush and color, but the most it keeps is the color of the stoke (I'm not using fill). (I've tried reverting defaults and syncing multiple times, won't keep the brush.)
Curves also seem to auto-clip. I've noticed they manually change shape at some bends/between points by shape with the brush I'm working with- my issue is different though: depending on how I've zoomed on the curve, the appearance is different. It could be connected by a solid line at one percentage, and have sharp missing points/breaks in the line at others.
(Some examples below.)
