I’m not sure what a flatpak version could possibly do any better than the version I use.

The official OBS flatpak supports more codecs and integrations than some distro packages.

Stability is also a factor, especially on rolling or cutting edge distros. Fedora RPM release of Blender did not work for me at all with an nvidia GPU, for example.

If you have multiple monitors with different refresh rates, you’ll notice immediately.

AFAIK no systemd -> no flatpak -> don’t recommend to newbs. Say what you will about flatpak, but it is the official distribution method for some popular pieces of software and large GUI software generally works better through it (in my experience) - think Blender, GIMP etc.
