Had that as well on macOS. Problem went away when I switched the system from dark mode to light mode (or the other way round, don’t remember). But generally, I have to use Premiere for work anyways. For personal projects I prefer DaVinci Resolve though because, in my experience, it’s the most stable and performs the best of any program I’ve tried.
I think Mint is mostly for the “I have a PC that’s a few years old and want something easy and reliable to replace Windows with” crowd. Because it works great for that. It’s the perfect beginner distro.
