• Steamdeck / gamepad UI elements have unusual latency / lag when navigating all of the menus except for the "guide" side-bar menu (which causes the background to become transparent for some reason):

• The guide system menu doesn't respond to my controller at all (Xbox Series X|S Hyperkin Duke Cortana - running via the xone driver); for visual context, a screenshot:

I had to use the mouse to get to "system," click towards the bottom of the direction I wished to go, and mash the D-pad to take the screenshot above.

I'd consider these to be basic deal-breakers (primarily the slow UI and non-working inputs) for using this mode; I want to, but I can't with the way it is.

Steps for reproducing this issue:

1. Opt-in to the Steam client beta
2. Append the -gamepadui '$@' %U launch argument to the Steam .desktop file, and run it
3. Navigate the new menus with an Xbox Series X|S controller
