Hi Devon,

I don’t think the NS port supports modifying the mouse pointer. It
looks like it could probably be handled with custom NSCursors.

If your colleagues aren’t seeing any issues with 10.14, it’s probably
a fluke. Either that or you’re doing something, or running something,
which is prodding the bugs in the display system directly.

In macOS 10.14 Apple dropped the drawing mechanism we used, and I’ve
been unable to come up with a suitable alternative.
