1. I'd like a private way to report bugs as I'm an employee and I can't publicly disclose my models.
2. I took a screenshot of a corner of my model that hopefully shows the problem. I've pulled my design history back. The white surfaces should continue on the top as it is all one solid body, but it's as though the top surface isn't there. Moreover, some entire features are invisible. Sometimes when I switch display modes, it shows up correctly, but then disappears again. When I pull my history forward, the model appears correctly.
