Technical Display- line doubled and flickering issue

I have some issues with technical display. The lines appears wobbly, doubled and flickering. There isn’t a problem with shaded view though.

Is there a way to fix it?

It could be the object… can you select just one of the objects that show this issue and use the Export command to save just that object? Then post it as it’s own 3dm please along with a screenshot of what you see in the default technical display mode. You can reset the technical display mode in Options>View>Display Modes>Technical

Hi Brian, thanks.
I tried but don’t think it’s an object issue…
any other possibility?

Is your object very far from the world origin?

Can you post that object as it’s own 3dm please by using the Export command? This will help in figuring out what the issue is.
