Bug ID: 413173
Summary: Krita 4.2.7-beta1 Relative Zoom Mode laggy on Pen
Display
Product: krita
Version: 4.2.7-beta1
Platform: MS Windows
OS: MS Windows
Status: REPORTED
Severity: normal
Priority: NOR
Component: tablet support
Assignee: krita-bugs-n...@kde.org
Reporter: snopm...@yahoo.com
Target Milestone: ---
SUMMARY
Relative Zoom Mode is smooth and fast if I use my mouse but laggy when using
the stylus on the Pen Display(XP-PEN Artist Display 22E Pro.)
STEPS TO REPRODUCE
1. Hold CTRL+Space, then use stylus on the pen display to activate Relative
Zoom Mode to zoom in and out.
OBSERVED RESULT
Zooming in and out with a Pen Display using Relative Zoom Mode produces a very
laggy canvas, especially when zooming out. At times it looks like the canvas is
frozen in place only to update/refresh in a different location. On the
contrary, if I use my mouse to operate Relative Zoom Mode it works very
smoothly and fast without any lag. Using the Pen Display to in Pan Mode or
Rotate mode is fast and smooth, only the Relative Zoom Mode seems laggy.
EXPECTED RESULT
Relative Zoom Mode on using stylus on Pen Display just as responsive as using a
mouse.
