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.
