The virtual keyboard isn't used while gaming in regular desktop Linux. That is a steam issue, specifically a steamdeck issue since a regular desktop would use the physical keyboard to type in Skyrim.

I know about the OS the deck is running and that it's an arch form, but it's not a Linux issue, it's a steam deck issue since non steamdeck desktop Linux pcs don't have that issue because they use a physical keyboard.

What you are saying is like me saying that the inability to read Chinese is a human issue because I can't read it and in human. Naaah.
