I’m using Rhino 6 on a mac with a AMD Radeon HD 6750M graphics card (which I know is not supported). Things seem mostly fine so far, and nothing crazy has happened but lines occasionally do “vanish”, then come back if I move the camera around. They are there, just not showing up. Is there any workaround for this besides constantly using SelAll? Very new to Rhino, and did this jump to Rhino 6 so I could better follow Rhino’s tutorials.
