I have a hidpi laptop
It has 2254×1504.

I use KDE plasma with wayland with 200% scaling. It's arch linux.

When I run the game it is blurry. For example terraria.
It seems that game thinks that my screen desolation is 1128x762 and I can't change it to higher resolution.

Do you have a spotty connection? You managed to post your thread four times.

Maybe try X11 instead of wayland?

Wayland seems to have problems with scaling. Don't think it's the game's problem.
