MRTK inspector renders incorrectly on Unity 2019.3:

Wow lol @keveleigh, we might want to wait until 2019.3 gets out of beta
@Troy-Ferrell No disagreement here haha! Figured I'd log in case it ends up persisting past their beta :)
Yea leave it for tracking
I believe this is fixed by Unity in latest 2019.3 (Note I used #7193 as starting point)

Yep! I think it was fixed ~2019.3.0f4. Thanks for closing this out!
One outstanding graphical error I've seen though is the controller mapping profile.
