I think that might be because I'm making the game run by default at the highest resolution when you start it for the first time, because many players weren't picking the highest resolution and were seeing a low quality/pixelated version of the game.
And no worries, you didn't seem grouchy and I appreciate the bug report because my goal is to have a very polished game in anticipation for the next year's Steam release.
I can try to check on first startup if the user has an ultrawide screen, or at least instead of defaulting to the absolute highest resolution to instead default to the highest resolution that's not ultrawide (16:9 ideally, because the UI is designed for that) 🤔
