Video of speed linked to size, quick movement
SUMMARY
Brushes using 'speed' modifier have detection patches where they appear to
think brush move very slow - means that any brushes with variant based on speed
are rather unusable.
See video for obvious example with speed linked to size.
I am using Samsung tab s9 ultra, with 16gb ram and snapdragon 8 gen 2, which
does not experience slowdown in other areas of the app. Pen speed does not have
the issue in other drawing apps, so I believe it is a krita issue.
STEPS TO REPRODUCE
1. Make brush with a factor linked to brush motion speed
2. Use the brush at fast speeds
3. See patches of detected low speeds
OBSERVED RESULT
Jittering in brush thickness when linked to speed, with larger blob appearing
as if brush is slowing for split second
EXPECTED RESULT
With brush used in example, should be consistently smaller at faster speed

ADDITIONAL INFORMATION
Can't copy Info from the bug report tab as it seemingly gets saved to krita's
built in clipboard, not the global tablet clipboard - thus cannot paste the
text outside of krita app
