SUMMARY Fill tool uses the full colour in comparison. This means you can fill an area of transparency and only parts that were previously the same colour will be filled together. STEPS TO REPRODUCE 1. Use erase mode to erase separate colours. 2. Use fill tool to fill in the transparent portion. OBSERVED RESULT Only previously contiguous areas will be filled. EXPECTED RESULT Transparency is transparency and should fill as one consistent area. SOFTWARE/OS VERSIONS Arch Linux - 5.9.12 Krita - 4.4.1 - packaged QT5 - 5.15.2-1
