Bug ID: 423768
Summary: Brush presets docker being too large affects
performance of brush rendering and UI.
Product: krita
Version: nightly build (please specify the git hash!)
Platform: MS Windows
OS: Microsoft Windows
Status: REPORTED
Severity: normal
Priority: NOR
Component: Dockers
Assignee: krita-bugs-n...@kde.org
Reporter: i...@ralek.art
Target Milestone: ---
If the brush presets docker is too large, it can slow down the rendering of
other aspects of the program.
For instance, drawing any line with any brush engine with either the mouse or
pen will delay the rendering of the stroke anywhere between 20 and 100ms. This
can be jarring for drawing.
It's worth it to note this delay in rendering only occurs if any brush preset
is highlighted in the brush presets docker. If the program is recently opened
and no preset is selected, canvas rendering is as expected.
The brush preset docker's size also affects the overall UI performance, slowing
the rest of the UI down to as low as 15 fps.
