Thanks for the tip. :) I haven't tested with AMD graphics -- not sure if
anybody else will have.

I don't think so.  Somebody was interested in updating to a more recent
Nixpkgs a few weeks ago but I don't think they got anywhere.  I was
planning on doing it once I got some stuff I have locally cleaned up and
committed.  If you wanted to have a go that'd be great, and I'll happily
provide any help you need. :)

In particular, if you were to run into any failures due to versions of
dependencies being too old or something, we might need to sync with
upstream Nixpkgs first.  If that's the case I can prioritise getting
that done unless you'd like to try that as well -- I'd expect it to be
easier than updating chromiumOSPackages because we don't heavily modify
Nixpkgs, just add to it.

Nice to make your acquaintance!  I'm Alyssa, and I'm the main person
behind Spectrum at the moment.  I hope you stick around. :)
