I play a lot on the Steam deck and it runs pretty well, even if the texts are a bit small.
There is only one thing that is quite annoying.

The search and encyclopedia icons should not be activated on hover. If you accidentally put the mouse on the magnifying glass, the whole screen immediately goes black and the keyboard opens. With the Encyclopedia it is similarly annoying when the large window jumps open, and you can only close it again with the X.

Would it be possible to disable the hover effect on the menu? Or at least turn it off for the two icons or delay it for e.g. one second?
Or maybe the option already exists and I didn't see it?

But either way, thanks for this great game.

The optimization of steamdeck is still in progress, but the issue you mentioned does deserve priority treatment and we will optimize it as soon as possible.
