Legion go Steam game mode at the wrong resolution

I just installed bazzite on my legion go, everything looks fine on desktop mode but steam game mode doesn’t fill the display as if it’s running at the wrong resolution. Can’t find anything in the settings to change it so I’m hoping I’m missing something simple.

For future reference: I reinstalled the KDE version of bazzite and everything seems to be working fine. Original install was Gnome, figured it would be more touchscreen friendly.
