SUMMARY Change the name of a layer(s), Krita doesn't recognize a change has been made to the document (and thus if that's all you're doing, the document can't be saved). Likewise for setting Guides Visible or Locked settings. There may be other settings that don't trigger a save document. STEPS TO REPRODUCE 1. Save a document 2. Change a layer name 3. Observe no 'changed document' asterisk OBSERVED RESULT Asterisk in title bar doesn't appear, document can't be saved EXPECTED RESULT Asterisk would appear and changes can be saved SOFTWARE/OS VERSIONS Windows: 10 latest macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION
Control + S and pressing the save icon saves the document for me. I agree with the asterisk, though
Apologies, you're correct that Ctrl-S does work regardless - I had tried that previously but my keyboard must not have registered it.
This is already fixed in 4.2 (fixed by commit 43f89ce8d9c13ee0c174), thanks for the report!
