[BUG] CANT CROP (Steam deck)

[Kusanagi942]

Hello, i actually get a Meta quest 2 headset and i wanted to stream it on my Steam deck. (the only solution that use usb cable that work i found) It does work well but it does show the two lenses. i saw that some people succeed to crop to show only one lens. But when i go to settings, its grey and i cannot crop. Do you know why and how can i succeed to crop? Thank you !
