OpenStudio geometry tab renders EnergyPlus example file surfaces as white
The file is AirflowNetwork_Simple_House.idf which is an EnergyPlus 9.0.1 example file. Importing the idf into openstudio 2.8.0 and clicking the geometry tab displays some of the walls colored white instead of the usual tan. My OS is Windows 10.
There is a similar post here, but that post is from 2014 and has to do with modifying the geometry using sketchup, which I have not done.
Post Script
The white walls also stay opaque when turning off displaying the walls.
