Logging in with you Steam ID has now been restored ♥
It might be some internal z-fighting on the the LOD submodel those props are using. I can't quite tell from the screenshot, but those are monitors, right? Try replacing them with another monitor model and see if it still happens.
Also just for reference jadebenn, while it's good practice to func_detail brushes using translucent and alpha masked materials, I'm fairly certain the compile tools do that automatically.
making the windows a funk_brush seems to have fixed it but i still dont know how this occurred in the first place i cant reproduce it outside of the afflicted file im reverting to a previous version just for my peace of mind
