--- Comment #15 from Tyson Tan <tyson...@mail.com> --- I've built Krita 3.0 Alpha locally, and things behave a bit differently now: 1. Krita's performance logging still fails, but it now shows "QFSFileEngine::open: No file name specified" instead. 2. Slowdowns still occur when drawing, but at least curves do not occasionally become straight lines anymore. But the canvas updates even slower. I can feel it updates only 4 or 5 times during a very long stroke. 3. It's so slow that I can see a curve stroke with zig-zag at its edge, then about 1 second later the antialiasing makes it smoother. 4. Appimage version uses GTK file dialogue. Local build uses KDE file dialogue. -- You are receiving this mail because: You are watching all bug changes.
