Rhino 8 semi-transparent display mode BUG

I’ve been using Rhino 8 for a while now, and honestly, I find it graphically a step down from Rhino 7. In a semi-transparent display mode, I’ve set the surface edges (including naked edges) to show in black. However, in the viewport, they randomly appear either black or take on the color of the surface itself — you can see what I mean in the video below.

Also, still in semi-transparent mode, surface selection doesn’t always work properly. Sometimes clicking in the middle of a surface does nothing — you actually have to click on the edge to select it, which feels really inconsistent.

Am I alone with this problem…?

I have the same issue with the surface edges changing color while moving the display, but it also occurs in fully opaque shaded mode.

Please run SystemInfo in the command line of Rhino, and copy-past its output here. Thank you.

Are you using an external graphics card? If you remove the external graphics card, does the issue you reported still occr?

Hi Jessesn. I am not using an external graphics card, but I am using monitors plugged into a USB-C hub. I should point out that this issue does not make Rhino unusable, but is a bit visually distracting sometimes. Notably, when I opened up Rhino this morning to test it, the surface edges are appearing as I defined them in display mode options without issue. I did not change my setup or monitor configuration, so I am not sure what fixed the issue.
