SUMMARY The selection tools in Krita (4.3. 4.4. nightly 12 Oct) have inconsistent/unexpected behaviour in subtractive mode. When one has no pre-existing custom selection on the canvas (i.e the whole canvas is selected hence paintable) invoking a selection in subtractive mode unintuitively selects whatever shape is being draw, rather than selection everything else on the canvas. This behaviour is unexpected for two key reasons 1) It has no distinctive behaviour compared to 'Replace' or 'Add' modes even thought it is a distinct mode. 2) The logical conclusion user makes "I'm SUBTRACTING this area from my paint-able area hence masking it off" results in unexpected result since what the tool actually does is the opposite of this expectation (When there is no pre-existing selection) Though, considering this seems to be how it has always worked I'm assuming this is more of a design thing than a bug. Still I think it would be something worth altering eventually since it would make more sense that way. STEPS TO REPRODUCE 1. Select lasso tool 2. Press S to enter subtractive mode 3. Draw around an object with the intention of removing its surroundings 4. Press delete OBSERVED RESULT You have deleted your object that you were trying to subtract from your selection EXPECTED RESULT You have deleted everything around your object. SOFTWARE/OS VERSIONS 4.3 4.4 Windows: Win10
I think the behaviour is logically correct though it can be confusing when first encountered. By 'lasso tool', I assume you mean the Outline Selection tool? In Steps To Reproduce, if I follow those steps excactly then everything outside the drawn selction area is deleted, i.e the Expected Result. I don't understand why you see the 'enclosed' object being deleted. If you want to discuss any aspect of application behaviour then the place for that is https://krita-artists.org/ where you can start a topic and exchange views and easily post screenshots to illustrate things.
I was planning to make one yes since I'm assuming it will be filed as not a bug. Also, yes the outline selection tool. It is surprising to me that you are getting opposite result, though. Maybe I need to try deleting everything again and get a clean install of krita.
Please reset your configuration: https://docs.krita.org/en/KritaFAQ.html#resetting-krita-configuration and check again. Make sure to check the Tool Options to see if 'S' really changes the selection tool mode; in my case it didn't do anything, so I had to change the mode myself.
