Can anybody provide some more details on what would be required to finish this work of getting XQuartz off libXplugin?  I would love to help, if I can.

The issue is below us in CoreGraphics and won't really be fixed on Apple's side as doing so would fix this case but cause bad performance penalties for every single other case out there.  The real solution is to get XQuartz off of libXplugin and start using more modern macOS APIs (eg: finishing up libxcwm), but there's not really anyone actively working on that right now.
