I've gotten Terragen running using Bottles, and it does seem to work well, but for one thing. The node network looks wrong, too translucent and and kind of distorted. It's not a major deal, just makes it a little harder to read, but it would be nice to iron this out. Not sure when this started being a problem, as I've hopped between Windows and Linux a fair bit during the last year, but it definitely wasn't always doing this.
I'm not getting any errors when I open Terragen, but I figure this is probably caused by some sort of missing dependency. Any idea what might need tweaking to fix this? I'm using KDE Neon, but have also seen this on Mint.
