Cannot change internal display resolution

I'm running Bazzite 41 on a GPD Win MAX 2 (2024). When I try to set the resolution of the internal display from 1600p to 1200p, I only see black and it reverts to the previous settings since I'm not confirming the change. I can change the resolution of an external display, and I can also change the resolution of my internal display in Linux Mint 21.3.

What could be the issue here?
