Bug ID: 429637
Summary: Discrete canvas rotation mode is skipping an angle
Product: krita
Version: 4.4.1
Platform: Microsoft Windows
OS: Microsoft Windows
Status: REPORTED
Severity: normal
Priority: NOR
Component: General

Target Milestone: ---
SUMMARY
Using discrete canvas rotation mode skips an angle in rotation.
It's all time present but it skips different angles so you might need to rotate
all 360degs to find it.
For me it always starts around 0 it goes to 15° then if I want to go back it
goes to -15° so a 30° step while all the other angles have a 15° step so this
is how it looks:
... -45° <- -30° <- -15 <- 15° -> 30° -> 45° ...
After rotating around for a bit the 30° step shifts to a different angle for
example to: -60° -75° -105° -120°
STEPS TO REPRODUCE
1. Use discrete canvas rotation
2. Watch how angles change
OBSERVED RESULT
Angular step is irregular at one point during rotation going from 15° to 30°
just for one angle change the rest is 15° again.
EXPECTED RESULT
Same step for every angle change (in this case I believe Krita uses a step =
(360° / 24).

(I hope this is a bug, if it's a feature I'm sorry for the report)
