Why are all UI inputs disappearing

Recently my UI seems to be malfunctioning. All of the input fields appear blank, until I hold down a mouse click, which causes the values to reappear. This bug also seems to affect the UI in my viewport as well, the various asset color coding is also gone. I can still change the values and input but using the editor without being able to see what I am doing is making life difficult. Anyone else running into this issue in 4.21?

Here, same problem.

Me too, here i post a tweet about this… bug?
