Bug ID: 419328
Summary: Canvas zooming framerate performance terrible within
the last several builds.
Product: krita
Version: nightly build (please specify the git hash!)
Platform: MS Windows
OS: MS Windows
Status: REPORTED
Severity: normal
Priority: NOR
Component: General
Assignee: krita-bugs-n...@kde.org
Reporter: i...@ralek.art
Target Milestone: ---
Within the last 4 or 5 builds, framerates when zooming have been performing
absolutely terribly relative to a week ago. While I would normally get 110+ FPS
when zooming, I am now getting on average 13 FPS on both OpenGL and Angle.
This doesn't affect rotating and panning, which still perform nicely at over
100FPS.
It's still present on an empty canvas, and a small resolution canvas.
