SUMMARY
krita-nightly-x64-5.1.0-prealpha-0c31a5bcc5

Comparing 3.1.2 with the previous version and the windows independent version of gmic-qt, I am sure it has problems.

It is found that the GIMP version also has the same problem. I'm discussing with David:

Comment 2 amyspark 2022-05-31 22:52:21 UTC 
Marking as RESOLVED UPSTREAM because I've verified (after fixing 453477) the issue resides in upstream's widget management.

Based on the preview's usage of gui_merge_layers, I'm inclined to think the stroke is being rendered with an offset while ignoring the original layer's position, which should cancel the offset and thus render them in line. I don't understand G'MIC's stdlib language, so can't test much further.
