when using distrobox why does firefox not always use nvidia driver.

[Certainty1396]

I installed nvidia-vaapi-driver in distrobox, but every time I distrobox enter tumbleweed-pkg firefox chooses intel and nvidia driver intermittently. My device is a laptop with optimus and I force using nvidia in host system.

Oh, It is distrobox's problem, not driver's problem. The latest distrobox fixed this problem. This is because distrobox didn't integrate nvidia file into guest system in time.
