On hardware like that, it might be be necessary to disable opengl :-( (In reply to Alvin Wong from comment #1) > What operating system are you on and what smoothing options did you have > enabled? Which tablet are you using? The operating system is macOS Sierra, version 10.12.5. I was using no smoothing options when I made the reference picture, but after testing, I found that it happens regardless of smoothing or stabilizing option. The tablet I'm using is a Wacom Intuos Draw. After disabling open gl, I found that the angular lines aren't as bad, but they are still there. Ignoring the issue with the lines(which may be an issue with my equipment), I think that this is a great program, though. It's a bit confusing with all the features, but I think it's the best free program I have found so far -- You are receiving this mail because: You are watching all bug changes.
