I've been running this on an old Mac Mini Late 2012 semi-successfully. However it seems some menus get blurry and some apps none of the art elements will load. Guessing it's things that try to call on Metal. Anyone seen or aware of a fix for these bugs?

It’s an normal behavior I would say. The graphics acceleration is still new and sometimes it can be unstable.
