Hello! I have quite specific problem and i can't really look it up bc i don't even know how to even define it. I am wondering what could be the cause of it.

The problem in question is that every some time, the brush stops painting. It isn't anything related to layers, selections etc, because i can temporarily fix it by either changing size of brush, or changing stabilizer settings. The problem started after i first used stabilizer, so i stopped touching it, but it still occurs, sometimes right away from the program start, sometimes long into the drawing. The lack of brush strokes is usually triggered by using "undo", and other options (that i don't recall rn). Not only it is unresponsive, other times also there's no difference between drawing and erasing, no matter what i pick it will do what was first chosen, and do it without pressure sensitivity (one time it even erased through all layers at once). So you can imagine it is a bit annoying, but it's not anything urgent haha

Why are you still using Krita 4.1.7? I don't even remember when we released that, so old it is...
