do you have snap-to-pixel activated in the snapping mnu? (shift+s)
(In reply to wolthera from comment #1) > do you have snap-to-pixel activated in the snapping mnu? (shift+s) I don't use it.
Oh yes, the woobly rectangle tracing tool or rectangular selection. It's an aesthetic bug I noticed and that appeared during Krita 5.x dev. This bug doesn't exist for 4.4.8 and under (I just had a check). For reproducing: the bug is not visible at 100% and 50% zoom of the viewport; but almost all other non-discrete zoom will trigger the woobly tracing easily.
