Thanks for that fast reply. I was scared.
I just found the error: user error = Do not set Preferences > Near Clip Plane to 0.
Context: In a prior thread I asked about help, meshes were getting clipped off, thus I couldnt zoom in enough. A mod said I could change the Near Clip Plane, but shouldnt.
(I didnt know why, and the change doesnt occur until restart. So I set to 0 to test. Forgot it was this. Thus I was surprised.)
Now I set it back to 10, and the normal display is back.
I’ll wait a little while if someone wants to give an explanation (to claim as the solution) about why Near Clip = 0 does this (or why 0 is allowed), and what is the lowest safetest number to use? Ty
