<rant>I hate Flatpak with Nvidia. It takes forever, because the driver is installed in multiple versions. I run `flatpak remove --unused` everytime and still... On my system are only a handful of Flatpak hpps installed, because most of the stuff is native on my system.
Unrelated to Flatpak: Each time the Kernel updates on the native package manager, the update takes ages because Nvidia driver needs to be installed with DKMS as well (twice, for each Kernel once).</rant>
