Checking - thanks. @Tom_P - this looks incorrect to me; at least, it does not corresond to Rhino for Windows behavior. I assume it is locked out because it is copied from default Rendered which also does not let you change this on either platform, but once copied, it ought to let you play. I guess, for now, (obviously) start with Shaded… RH-69505 Display modes- copy of rendered is not fully editable
I’ve looked at it, yes… Unfortunately bugs are not fixed in a first-come-first-serve order… They are prioritized based on specific criteria. Things like display mode settings glitches (especially ones that only happen on the Mac) tend to get pushed down the list pretty far.
That being said, I will look into this right now, since you’ve got my attention
