Issues with the gamescope on a dual-GPU laptop

Hi

I have a laptop with an integrated AMD GPU and a dedicated Nvidia GTX 1650. My Cachy OS version is the desktop version with GameScope configured to start on boot. I don’t have a mux switch.

It works correctly for displaying when I’m using it on the laptop screen. However, when I connect to an external screen via HDMI, I have problems; the screen is only displayed on the integrated screen, and I can’t select the external screen. Before, I used the export-gpu command and selected the GPU I wanted to use, and GameScope would start on the selected one. However, after some Cachy OS updates, I can no longer use this command.

Currently, how do I handle screen selection when I’m inside GameScope?
