Native packages? Sorry.

Sorry for what? I’m trying a fresh install of Bazzite so the distro prefers flatpaks.

Probably best that you do the same (installing packages in the FS overlay kind of starts to defeat the point of containerization). You could try installing it with a distrobox and then exporting the app—see if that fixes your loading issues.

I run Bazzite on a gaming laptop from 2015, and I haven’t noticed any particularly long load times. Do you have some browser extension that are maybe causing issues?

My only extension is uBlock Origin but it isn’t the problem (I uninstalled it to test and nothing changed). Thanks for your suggestion, I’ll try to play with distrobox (I’m new to Bazzite and immutable distros).

Distrobox will introduce a startup lag of it’s own. I would rather reccoment (seriously this time) something like nix (it is officially supported for your distro) or junest.

Nix might have been removed. I’ll have to check, but I feel like the ujust command forv setting up nix went away a version or two ago.

But I think you can set distroboxes to run at startup, so you’d never know the difference when it came time to actually launch the program. Right (correct me if I’m wrong)?

Maybe, I do not use bazzite and cannot check. But it used to be a feature. You can, of cause, start distrobox at startup, but literally running almost two operation systems might not be the best for performance and RAM usage.
