Hi @Gijs, this topic just reminded me of the Windows single line pixel scaling issue. I probably missed it, but is there a YouTrack or any updates on this? I’ve been increasingly using Rhino 8 in production lately. And it’s quite jarring jumping back and forth between Rhino 7 (sharp GUI lines) and 8/9 (fuzzy GUI lines) at 125% Windows scaling 
Edit: Sorry I think you already reported this YouTrack over here. As you were.
