I have a question with Painter 2021: there are green rectangles appearing on layers at times, but especially when i join one or two layers together. this has never happened in Painter 19 (last version i owned) . can anyone tell me why? there doesn't seem to be any logical reason for this
Can you add a screen capture?
Do the green rectangles stay and print? or do they go away after you do something? Often can be simply no screen refresh via s/w and/or video card driver....when appears, try doing a major zoom in or out and back to 100% to verify screen refresh.
