Serious camera issues in 8.5
this has happened to me a few times now. The cameras mess up - they flicker between top/side/perspective when I zoom or tumble or track. They also have issues switching from wire to shaded. It's serious enough that it makes it unworkable. I'm using the default cameras and have deleted the pref folder, but it's just happened again.
Any easy fix for this, if anyone has seen this before?
