Rhino 8 showing open surface edges as heavy lines when zoomed in

I’ve been having an issue controlling surface edge thicknesses in Rhino 8 - it seems to be defaulting to showing open surfaces (not closed polysurfaces) with thick edges, but only when zoomed in close, and not always. I’ve set my surface edges to the minimum but it does this anyway. Nothing seems to defeat this graphic behavior. Any thoughts on how to fix? Thanks

Hi Lowney - can you save a simple example - jusat a box or plane or whatever, at the zoom level that shows the problem and post that? Please also copy/paste the results of the SystemInfo command in Rhino.

Hi Pascal - here is the info and an example. My Rhino is set to use the NVIDIA GeForce driver. I notice that the open edges get heavy when I click on them in particular, but also sometimes on their own depending on zoom level. Notice the closed polysurfaces do not have this. Thanks, Matt Winkelstein
