Hi,
I’ve had this problem for a couple of months now.
Basically, my display modes which have Surface Edges toggled ‘On’, the edge flickers in and out as a zoom and rotate around my model. I want my edges ON. I’m using shaded mode mostly, but this also happens in Arctic and Rendered too.

I am not sure about MAC
your 575 pro card is released in 2017 and it support opengl 4.6
but according to your systeminfo, opengl version is only 4.1 (released in 2010)
I think something might be wrong with your graphic card driver.
I am up to date with my Mac OS updates.So, I’m running the most recent OS which would be updating the graphics drivers. What do you mean by ‘something wrong’?
your 575 pro card is released in 2017 and it support opengl 4.6
but according to your systeminfo, opengl version is only 4.1 (released in 2010)
I think I found the reason behind opengl 4.1
the 1st answer is pretty clear.
Since rhino’s min requirement is opengl 4.1 I think your imac will work fine.
There is no way that some random line display depends on opengl 4.6 not 4.1
The prolem may caused by other things instead of your video driver.
Please check your model size/unit and check the xyz coordinates of the wall corner.
is xyz too big?
That is a bit misleading in our SystemInfo command. Mac OpenGL only goes up to 4.1. If you have OpenGL tessellation turned on in the OpenGL settings for Rhino, try turning it off. This may help with the flickering.
Hi! That fixed it! What does having Tessellation turned on do anyway? Will I find differences in the running of my program with it now checked off?
I got the link here.
GPU tessellation is a technique for drawing wires in OpenGL that makes display quite a bit faster. Unfortunately this feature never really worked very well on Mac and I probably should have made it a Windows only feature.
