I don't have experience with NVIDIA Optimus, but according to
https://wiki.debian.org/NVIDIA%20Optimus#Using_NVIDIA_PRIME_Render_Offload, and
assuming it's up-to-date, it looks like passing those environment variables
(__NV_PRIME_RENDER_OFFLOAD=1 and __GLX_VENDOR_LIBRARY_NAME=nvidia) is expected
from the user. Has this changed?
Is there a way for for a strictly-confined snap to detect that it's running
with the PRIME profile, and set those variables accordingly, maybe?

Thunderbird is a free and open source email, newsfeed, chat, and
calendaring client,
that’s easy to set up and customize. One of the core principles of
Thunderbird is the
use and promotion of open standards - this focus is a rejection of our
world of
closed platforms and services that can’t communicate with each other. We
want our
users to have freedom and choice in how they communicate.
