SUMMARY *** With a group, hidden or locked layer selected in the layer stack the polygonal selection tool does not work, it lets you start and complete a selection but it disappears after completing it. It functions normally on paint and mask layers. None of the other selection tools seems to have this issue. *** STEPS TO REPRODUCE 1. Select a group hidden or locked layer in the layer stack. 2. Make a selection using the polygonal selection too. OBSERVED RESULT Selection disappears after completing it. EXPECTED RESULT Selection stay.
This was first reported at https://krita-artists.org/t/polygonal-selection-tool-does-not-work-with-group-hidden-or-locked-layers-selected/39927 I can Confirm this for the Apr 18 5.1.0-prealpha (git 4205530a30) appimage on Debian 10, for the Polygonal Selection Tool - Pixel and Vector selections Other selection tools do not have this problem. The 4.4.8 appimage does not have this problem. For locked and invisible layers, there is a warning notice when the polygonal selection is completed. For a group layer, there is no warning.
