Static Lines on macOS with wxPython 4.2.1 do not render properly

[facelessuser]

Operating system: macOS 13.3.1 wxPython version & source: pypi 4.2.1 Python version & source: python 3.10 and Python 3.11 (from Python.org installer)

Description of the problem:

Horizontal static lines do not render on macOS. This was apparently present in at least the 4.1.X series, but now vertical static lines render quite poorly.

It seems unlikely this is due to anything in wxPython. Can you please test in wxWidgets and see if you see the problem there? It looks like the samples (e.g., the widgets one) have wxStaticLines, so you can probably just compile wxWidgets and the samples.

You are likely right that it is related to wxWidgets. I will have to see if I can make the time to compile wxWidgets and go that route of validation.
