Bug ID: 422367
Summary: Android sents touch events as mouseclick, making
'touch painting' config useless.
Product: krita
Version: 4.3.0-beta2
Platform: Other
OS: Android 9.x
Status: REPORTED
Severity: normal
Priority: NOR
Component: General
Assignee: krita-bugs-n...@kde.org
Reporter: griffinval...@gmail.com
Target Milestone: ---
SUMMARY
When I turn off touch painting in the configuration, Krita still receives
events from my palm resting on the canvas. I suspect Android+Qt is transforming
these touch events as mouse pointer events. We might need to block mouse-events
on the canvas as well. The tablet tester, nor the tablet logging give any good
feedback here (both on my laptop and on the android device, touch is given as a
mouse event), we might need to adjust them to tell us about touch events too.
STEPS TO REPRODUCE
1. Turn off touch painting in the settings.
2. Draw something on canvas.
OBSERVED RESULT
Observe how spikes will appear between palm and stylus, due to krita not
blocking the palm/touch event.
EXPECTED RESULT
Expected result happens when turning off touch system-wise.
SOFTWARE/OS VERSIONS
Android 9 tablet. Google play version.
