--- Comment #3 from Ahab Greybeard <ahab.greybe...@hotmail.co.uk> --- I don't get a freeze when using the Delete key in this situation when running the 4.2.1 appimage on Linux Mint 18.3 I've just looked in the manual ( https://docs.krita.org/en/ ) and found out that Shift+Z will undo the last segment of a polygonal selection (and other polygonal constructions). Does using the Delete key act to Clear the layer in other situations i.e when not constructing a polygonal selection? Can you try the latest 4.3.0 pre-alpha appimage from https://binary-factory.kde.org/job/Krita_Nightly_Appimage_Build/ to see if you still have the freeze in this situation -- You are receiving this mail because: You are watching all bug changes.
