Bug ID: 361619
Summary: Input event lag/drop-out when OpenGL is ON with large
window
Product: krita
Version: 3.0 Alpha
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: major
Priority: NOR
Component: OpenGL Canvas
Assignee: krita-bugs-n...@kde.org
Reporter: tyson...@mail.com
In Krita 3.0 Alpha (Krita-3.0-Alpha-master-e5109c2-x86_64.AppImage), when
OpenGL is ON and Krita's window is large -- 1920x1080 maximized window, or a
windows that is almost that big but not maximized, I can notice input lag from
my graphics tablet and mouse. Some curves I drew even has straight line
sessions in them, probably due to event drop-out.
When Krita's window is smaller -- around 1280x800 or 960x1080, the lagging
seems to be much less noticeable. When OpenGL is OFF, the lag didn't happen at
all.
I will upload screenshots and tablet logs for each testcase.
Reproducible: Always
