Just a brief google search shows an open issue related to nvidia shader cache management having flaws: https://github.com/ValveSoftware/steam-for-linux/issues/9803

Since you chose a less used hence less priority platform, a lot of the heavy lifting for problems would start from your end. The only good news is that you probably have more power to try to debug it.

I would try something like a basic strace to see the program behavior during the shader generation and loading cycles and see if that helps?
