View error? Vanishing lines? Wrong key combination/Command?

Rhino Rhino for Mac
1

Hi there, by accident I hit the wrong key kombination or command or did something else.
Now the file I am working on and also all other files I am opening in Rhino 7 look like this, see screenshot.
Any idea what I can do to remove the (vanishing) lines?
Thanks!!

Hi Dennis,

Can you type SystemInfo in the command line and send the results?

These artifacts can appear a number of ways, the most common is an older version of Rhino on a older Mac with a Radeon video card. Unchecking GPU Tessellation often resolved it.

If you are up to date please send us the file and add a link to this thread in the description.

Hi:
I just looked at you SystemInfo.

In Rhino 7 > Settings/Preferences) > OpenGL, uncheck the option for using ‘GPU Tessellation’.

You may need to Quit and restart Rhino.
AMD’s gpu drivers are a bit dodgy…

Any luck?
