Bug ID: 508946
Summary: (Rebound) tablet rings can "flicker" between two
states easily
Classification: Plasma
Product: kwin
Version First 6.4.80
Reported In:
Platform: Compiled Sources
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR

SUMMARY
I'm about to leave for Akademy, so I can't fix this immediately but plan to
before 6.5's release.
This is very repeatable, not just by holding down your finger and slowly moving
but also during "fast swipes" where you complete many rotations at once. You
can notice - for example, in Krita's canvas preview - that the zooming
"stutters" like its quickly pressing and unpressing the bound keybind. (Haven't
debugged to see if it's actually doing that yet.)
I'm certain this is because of my terrible rotation detection code :-)
STEPS TO REPRODUCE
1. Bind a tablet ring to two keybinds, e.g. zooming in an application
2. Complete "rotations" (depending on the speed you set) and notice the odd
stutter here or there
OBSERVED RESULT
It stutters a bit like the rebind can't decide whether it's a full "rotation"
or not.
EXPECTED RESULT
It doesn't obviously stutter.
