--- Comment #1 from Jo <jo.y.v...@gmail.com> --- Because of what I wrote in paragraph 2 in my previous post, I downgraded to 3.1.1 Right now I need Krita and cannot experiment with a pre- alpha of v. 4. too dangerous if I lose my work. I really really hope version 4 is usable else I've to stick with 3.1.1. My macpro is powerful but I can't install Sierra or higher on it. In v. 3.1.1 everything runs smoothly as I paint and ...get no loud noise. I want not to break my machine because of 3.3.1 and it's _Serious performance problems_ with Mac os 10.11 -- You are receiving this mail because: You are watching all bug changes.
