Description Edward Mowah 2025-09-29 15:15:58 UTC 
SUMMARY
Various brushes lag when painting close to, or at the edge of the canvas.
Most noticable on canvas size above 1080 X 1080 (Iˋve noticed on even smaller canvas sizes when making quick strokes)
Brush size doesn't seem to matter since I've noticed it on brush sizes as low as 100.

STEPS TO REPRODUCE
1.  Paint close to the edge of canvas of various sizes.
2. Try quick strokes, long continuous strokes and slow painting. (Each has different result)
3. Try different brushs and sizes.

OBSERVED RESULT
Brushes lag close to, or at the edge of canvas, sometimes for a few seconds.

EXPECTED RESULT
No lag.

SOFTWARE/OS VERSIONS
Krita: 5.2.13

Also happens on 5.3, particularly egregious with the Quick Brush engine it seems.
