I think the fact is that most Linux users have a more technical background and work in the tech/IT sector. They know that filling a bug report requires a clear explanation of the problem, and steps to reproduce it, hence the greater quality of their reports.

But still makes me happy that even though Linux has a small market share, game devs actually start caring more for them. And a lot of this is also thanks to Steam, I don't think we would be here without their relentless work to make this happen and the Deck.
