Are you me and your friend is also me?

This sounds a HELL of a lot like my scenario. I swapped to Bazzite from Mint on account of NVidia/gaming issues, and IMMEDIATELY noticed a big improvement, but I’ve had a handful of issues dealing with the flatpak of JetBrains Rider, and Firefox for that matter.

One thing I figured out early was to configure permissions to allow Rider to access the filesystem outside of its sandbox. That seems to be not something that flatpaks are setup for, by default.

More recently, I found that flatpak sandboxes don’t inherit PATH or other global system variables. Which makes sense, but I haven’t figured out the solution yet.

I would definitely take a shot at another KDE distro, cause I also have liked KDE/Plasma (that’s what Bazzite runs, right?) more than I did Cinnamon, but I don’t know anything about what Bazzite does to get great NVidia performance for gaming, or how I might replicate it on a non-immutable distro.

I’m not really sure that being open source here means much of anything, but an SO alternative definitely sounds good. Thanks for the tip.
