Description Storm Engineer 2015-08-13 16:34:57 UTC 
When using stabilizer, if "stabilize sensors" is disabled, line endings will be jagged, as the size will decrease in wild drops rather than smoothly.

Reproducible: Always

Steps to Reproduce:
1. Enable stabilizer, and disble "stabilize sensors"
2. Draw fast strokes with a preset using size dynamics

Actual Results:  
Jagged line endings

Expected Results:  
Smooth line endings

Screen recording of broken behavior

I recorded a comparison between the broken stabilizer and other, workings forms of smoothing and no smoothing.

Hi Storm,

I can confirm the behaviour, but didn't we add that checkbox exactly to prevent this issue?
Comment 5 Storm Engineer 2015-12-11 06:11:19 UTC 
Well, it doesn't happen with weighted smoothing, so it is not supposed to happen I think...

Anyway, just wanted to mention I just tested and the issue is still there with freshly built 2.9 and a Wacom tablet instead of the crappy Genius I used when I reported this.

I can reproduce this also with Krita 4.2.0-pre-alpha (git 37c4f13) on Ubuntu 14.04 Unity.

Hi, 
here is a screenshot comparing the results between the "Stabile sensors" option disabled and enabled (Krita 4.2.0-pre-alpha (git 4fb7b5b) and (bottom) Krita 3.3.3. Instant Preview Mode was OFF).
