Gamescope not working Bazzite 42

I'm currently running a Ryzen 9800x3d and RX 9070XT on Bazzite 42 KDE. I have HDR enabled on the desktop and am trying to get games running under Gamescope so that I can use HDR in game also. I've tried Baldur's Gate 3 and Final Fantasy XVI. The game tries to load, and usually makes it to the splash screen, and then crashes back to desktop and play button on Steam turns green again. Here is the launch arguments I'm using:

MANGOHUD=1 gamescope -W 3440 -H 1440 -r 165 -e -f --hdr-enabled --adaptive-sync --force-grab-cursor -- %command%

This worked fine on Cachyos, but isn't in Bazzite.
