Hi, yes, I have noticed your recent deep dive in rectangle drawing and I really appreciate that you found this issue as well, that gives a little more weight to my findings above.
I hope that raises the precedence of this issue in the todolist of the JUCE team.
Also, the resulting visual artifacts are very similar to what appears in the other topic: Int vs float rectangles with scaling: a proposal for Windows/MacOS consistency for JUCE 8 ,
but it seems to me that the problem described in this topic is of a different nature and doesn’t have anything to do with the int/float differences that come into play in that other topic. Do you confirm?
If so, then the issue described in this topic can be resolved for macOS, independently of what’s decided for the other one.
