Active geometry surfaces turn grey during viewport translation (V6 SR13)

Rhino Rhino for Windows
#1

OK someone tell me where to find the magic checkbox to fix this nonsense.

In the video below there’s a cube on a red layer. The viewport is set to Shaded. When I select the box, it shows the yellow edges (which is correct). But when I do any kind of viewport translation, such as orbiting as shown in the video, the box turns grey. If I deselect the box, it stays grey. If I the reselect, it turns back to red.

Why is the box turning grey!?

Note - this only happens to the selected object. Anything unselected remains the correct colour.

Hello - unfortunately, Parallels is not supported - precisely this sort of defect is all too likely via Parallels. Bootcamp will be a better bet.

I’ve used V5 with Parallels for years with no issue. Are you sure this is the cause of the problem?

#6

Extremely likely. V6 is completely different from V5 in terms of how the display is handled.

#7

Just a general comment for running Parallels - while still not supported, I’m told that you need to be running SR 14 or above to be able to see any text in a viewport.
