I’ve been daily driving Mint for about 2 years now and I still love it. I do a lot of work with Python including some data science, and it works well for all that. The one bug I can’t deal with is the fact that fractional scaling causes screen tearing in the Cinnamon DE because it still uses X. Because of this, I use Nobara on my gaming PC. My experience with Nobara has been that every update is a coin flip on whether or not I’ll get a new bug, but they’re mostly just minor inconveniences. Otherwise I like it a lot.
The Flatpak drag-and-drop thing I’ve seen before (even on Mint) and I think it’s because of permissions. Try installing Flatseal and monkey around with your Flatpaks’ permissions; it may help.
