Black areas showing up in 2017 Layout viewport

We have the same computer and graphics card. I went back to SU 2016, which was pretty annoying since I didn’t notice this issue until after I had saved several models in 2017 format. Having to switch them all back is a headache. Someone from the sketchup team asked for system info about this issue in another thread, which I sent to them in a PM, but they never replied concerning it.
