I managed to get the game's textures working well through Lutris with this script I found!

It'll compile and install latest mesa, just make sure you add the wrapper script to the command in the lutris config for the launcher and it should work great.
Managed to make it work first try with this script on my KDE plasma/debian testing setup after wrestling with the textures issue for several days.
I'm a professional and hobbyist C# .NET dev and I recently made the switch to a full Linux environment at home. I've gotten a great workflow setup with just VSCode and some extensions. I've actually found some ways to improve my workflow with VSCode vs Visual Studio and I'm glad I made the switch. The only thing I really miss is the phenomenal diagnostics and profiling I would get with a full Visual Studio install, but I'm getting used to using cli dotnet tools to replace that as well.
If you're going the VSCode route, feel free to ask me more questions on useful extensions or workflow tweaks!
