I agree with you there, installing new software on Linux can often be quite a pain if it's not available on flatpak. Repos will be out of date, appimages don't auto update, grabbing a binary has no easy way to add to the start menu or taskbar and also doesn't generally auto update.

Even if it is on flatpak then I often end up dealing with flatpaks annoying permissions blocking normal features like streaming my screen in a browser, which is even more obnoxious.

I still can't get hardware acceleration for video working on my laptop after months, videos players and browsers struggle to play back anything, something that works perfectly on windows with zero setup.
