Hi, > The split parts tool creates invalid polygons according to GEOS check > validity. This issue seems to have been discussed two years ago > https://issues.qgis.org/issues/12799 but it still persists today in master.
Also see last years' discussion: https://lists.osgeo.org/pipermail/qgis-user/2017-May/040007.html > To reproduce: > 1. Create a memory layer with multipolygon type > 2. Add a polygon > 3.

Currently the more robust way is to go with Bernhards' DigitizingTools version of "Split Features".
