Hi! I've been having this problem for 2 months, I've tried to work even with getting things deleted but there's no way :'
This only happens to me when texturing in hand-painted, after a while of texturing, when I want to go back a step with ctrl+z it doesn't go back a single step, but several steps, about 7 or 8 strokes are erased. For this I can try to not work with the ctrl+z, although it is very difficult, but the biggest problem comes when I save the file to close it, then I open it at some other time and part of the wall of the house that I texture is erased, it is erased uniformly in different layers. And with the new update some strokes that I have not painted appears. I share screenshots:
I have to add that I have had this problem in 2 different files, and it also happens to me from other computers, I have no idea what it could be :'(.
Thank you very much for reading me :))
