Conventional wisdom from previous releases involved deleting the view and recreating it. Unfortunately, that didn’t work in this project. Neither did resetting the view using the view cube!
Note: I’ve checked the transparency of materials and verified that ghosting and transparency are not at work here.
Because this was associated with a problem orbiting, I suspected CAD to be at the root of the problem. Turning off the cad import, which had geometry far from the origin, did not fix the problem, but it did resolve the orbit issue. With the orbit issue resolved, I thought I would try resetting the view. Right click on the design cube and choose “orient to a direction” -> TOP. Now the view is fixed.
Hope this helps someone else!
