Line type Display Issue - Double lines showing in sheet and model views

[bluelion]

I am getting this issue where there is this extra line showing when I apply insulation to a duct or pipe, its a solid line that runs inside it and runs around the perimetre of the duct or pipe.

Other instances are generally custom family's get the line too

When I print the the lines show properly and have no issues

I think I've heard of this problem before - did it start all-of-a-sudden? It may be the result of a graphics driver update. Otherwise, try toggling "Hardware Acceleration" under Options and see if that alleviates the issue.
