Do you know any equally easy alternatives?

If that's the issue, why it doesn't happen with all other flatpaks?

Nothing special, I don't think that's the problem since the lag is at every launch and it takes something like a minute to appear.

Oh thx for the info, I can maybe try with rpm-ostree in the case of lag. Nix is very good but I'm liking Bazzite very much for my needs, everything else seems working very good.

I use Orgzly Revived with Syncthing, it's pretty good

Ardour is the most complete and professional DAW in my experience, Zrythm looks promising.

Is it unusual to use retroarch via pacman and cores via RA utility?

Are you trying to get individual Roms to appear in steam as their own games? Does your command work outside of steam?

Yes both.

Hmm...looks like in my cores directory "/home/user/.config/retroarch/cores/" I only have .info files.

I'll try to learn more about SRM, EmuDeck was also recommended to me.

Thanks for this report.

SimpleXchat is the goat

Oh my old friend! 0o0

During games it works perectly, it is only in big-picture (for both controllers).
