ConstraintLayout 2.0 rendering problems

I am having the same issue after updating to 2.0.0, I believe this is an AS/Constraint Layout issue. Using version 1.1.3, for the time being, works just fine.

implementation 'androidx.constraintlayout:constraintlayout:1.1.3'

Ok, in my case this definitely looks like an issue with a project cache. Once I've cleaned it up (Build -> Clean Project), the layout preview started working just fine.
