SUMMARY When a users uses an eraser the blend mode in the top tool bar become erase, right after this if the user is using the fill tool same blend mode is carried forward. This results in users getting confused, the users can change the blend mode again to normal but, most often fill tool is not used with erase mode so it would be better if the blend modes are not in sync. STEPS TO REPRODUCE 1. Open Krita and a new document 2. Use any eraser brush preset 3. Now try to fill the canvas with some color with fill tool OBSERVED RESULT fill tool erases the whole canvas since it now has erase blend mode EXPECTED RESULT fill tool blend mode should be different than brush tool and it should be normal by default. It can however remember the last chosen blend mode by the user.
As far as I know, quite a few people use eraser in the Fill Tool. So it shouldn't break their workflow. And this bug is tightly related to the following bugs: https://bugs.kde.org/show_bug.cgi?id=359809 https://bugs.kde.org/show_bug.cgi?id=412060 https://bugs.kde.org/show_bug.cgi?id=410534 I mean that all of them should be resolved in a uniform way.
This is a wish. And yeah, it should be implemented together with the other two wishes/bugs. Phabricator task: https://phabricator.kde.org/T13347
