[issue42541] Tkinter colours wrong on MacOS universal2

[Kevin Walzer]

Kevin Walzer <wordtech at users.sourceforge.net> added the comment:

This bug is not present in IDLE 3.9.0 when built against the tip of Tk core-8-6-branch. Marc Culler has done some work to fix the visual artifacts, and the work continues. The problem here is that Apple's API churn continually breaks parts of Tk with each new OS release, and there is large amount of work just to keep things working reasonably.
