Bug ID: 363487
Summary: brush lags behind when making quick or long strokes
Product: krita
Version: 3.0 Release Candidate
Platform: MS Windows
OS: MS Windows
Status: UNCONFIRMED
Severity: major
Priority: NOR
Component: Brush engine
Assignee: krita-bugs-n...@kde.org
Reporter: will89...@gmail.com
Pretty much exactly what it says in the title. For whatever reason, Krita 3.0
RC1's brushes simply don't seem to perform as quickly as 2.9.11's for me.
Attempting to sketch in this version is clumsy to the point of near-unusability
for me, as the brush is a half-second to a full second behind whatever my hand
is doing. Drawing a line across the canvas results in waiting more than a
second for the line to catch up to the brush.
The canvas in question is here 2970x1620, so it's not like it's excessively
large or anything.
>From what I've seen, the issue appears to effect inking and sketching brushes a
lot more than painting and mixing brushes, so I think it might possibly have
something to do with brush size variance. Additionally, the issue appears to
get much worse when working within multiple nested group layers, resulting in
even small movements lagging behind for anywhere from a 1/2 second to more than
a second.
Please, let me know if there's any additional information I could provide to
help get this bug fixed!
