Bug ID: 412286 Summary: Occational short slowdown/freeze while painting Product: krita Version: nightly build (please specify the git hash!) Platform: MS Windows OS: MS Windows Status: REPORTED Severity: wishlist Priority: NOR Component: General Assignee: krita-bugs-n...@kde.org Reporter: acc4commissi...@gmail.com Target Milestone: --- SUMMARY git ddb3a87 Brush occationally (very shortly) freezes while painting. It's not a big problem but very annoying. The behavior feels like how it used to freeze on autosaving in old krita. STEPS TO REPRODUCE I'm not sure when it happens but 1 way to see the freeze is 1. Paint something (Bigger brush size would be easy to see what happens) 2. Undo it with ctrl+Z, and then paint something again. 3. Repeat 1~2. If you do the recursive process fast enough, it becomes obvious that there's a choppiness in brush moves.
