[PurpleRamen]

I had similar problems with Lutris, but never came around to fully solve them. Now I'm using the native debian-package, and never had any problem again. Flatpaks overall are working fine, I use them for portable apps on my mobile SSD. But the security can be a hassle on a hacking friendly-system which is doing too much outside the expected. So one should be aware that Flatpaks might be a tad different from native packages.
