Can't see selection boundary as I make it
When I use a selection tool, such as the Polygon Lasso Tool or Lasso Tool, as I make my selection nothing appears on the screen, no lines, no nothing. Once the selection is made, then the marching ants appear.
Same for crop tool, when I make a crop box nothing shows up, but if I hover over the edges of the the invisible box, i can drag it, etc. When I hit enter, then it crops image.
Using Mojave, PS 2019, iMac Pro.
Some things I have tried is a restart of computer, and a reset of all PS preferences.
I have a screen capture video here: Dropbox - psproblem.mov
any help would be greatly appreciated, I feel like I'm losing my mind.
