SUMMARY
when using liquify, performance is lower when i'm zoomed in. maybe this has to do with accuracy? seems to be unrelated to canvas size, as i tested it with double resolution and got a similar result.

STEPS TO REPRODUCE
1. use liquify
2. use it on different zoom levels

OBSERVED RESULT
further out zoom levels give faster results on liquify strokes in the preview mode/transformation not applied

EXPECTED RESULT
same processing time per on screen distance of the stroke

SOFTWARE/OS VERSIONS
Linux: Ubuntu 14 lts(updated to 18/current)
Krita: 4.3.0 prealpha git d03f5ae, not a new problem for me, also on windows

This is expected behaviour, this precision of the liquify changes with the zoom.
