Spent about ~5 hours drawing, one crash: Minimized the app to check photos, reopened artstudio and it was "loading" the file I was working on. File lost a bit of work.
Looks like a different issue than the past one, but this minimize-crash (also happens when turning the screen off) happened in previous versions as well, and is relatively rare. I might get a few of these a week or so if I have a heavy work week.
