Overlay.py demo not working on OSX?

Can anyone please confirm that the wx demo module "Overlay.py’ is working on OSX? When I run this and do a left-click and drag, no drawing activity appears on the screen. The debugger suggests that the correct routines are being called, but no “rubber band” rectangle appears.

Thanks
Eric

Hi Eric,

  Using python 3.7, wxPython 4.1.0, and MacOS Catalina, this demo

works mostly like I think it’s supposed to for me. The line
styles in the first Choice box work, but the background styles
don’t seem to. Color and line thickness selections are applied to
the overlay rectangle correctly.

I’m seeing the following when I run the demo.
