Bug Text elements become artifacted after exposing a child of GraphView in UI Builder

Having a weird issue when attempting to inherit from the experimental GraphView, where all of the text of UIElements (labels etc.) becomes artifacted. This issue appears to be very specific to the GraphView class; inheriting from other VisualElement classes doesn't seem to create the same issue.
The issue occurs when hovering over the item in the Library, or upon load of the uxml file if it contains a GraphView element. The issue persists until a script recompile occurs (or re-load of the editor).
This is on a fresh install of 2021.1.14f1.



Close-up:


This also appears to affect certain other windows (ones that I presume are using UI Toolkit):


Unsure if this is a me problem or an editor problem

 

Just re-tested this in 2021.2.0b3 and I was unable to reproduce it. Carry on!
