Bug ID: 399638
Summary: Noticeable lag when drawing
Product: krita
Version: 4.1.3
Platform: Other
OS: MS Windows
Status: REPORTED
Severity: normal
Priority: NOR
Component: tablet support
Assignee: krita-bugs-n...@kde.org
Reporter: wontoon...@gmail.com
Target Milestone: ---
SUMMARY
After the October 2018 update on Windows 10, when drawing with a Cintiq Pro 16
tablet (this may extend to all Wacom tablets; unsure) there is a noticeable
delay (around 1 ~ 1.5 seconds) between when the the pen is on the canvas and
the stroke appears on the canvas. This appears in both Krita 4.1.1 and 4.1.3,
and both tablet input APIs. This seems to be somewhat sporadic, but it
definitely happens very, very often.
On the Surface 4 Pro, this problem does not exist (I have tested 4.0, got the
Cintiq Pro shortly after-- and 4.1.3. I expected 4.1.3 to have the same issue
but it is not there, making me conclude that this is possibly isolated to Wacom
tablets).
STEPS TO REPRODUCE
1. Run Krita after the October 2018 update for Windows 10.
2. Make a line. It may take a few lines.
3. (Optional) Curse at Microsoft at the top of your lungs.
OBSERVED RESULT
Lag in strokes appearing on screen.
EXPECTED RESULT
Smooth drawing.
