Please describe your issue in as much detail as possible:
I am attempting to stream games from my CachyOS host to a Steam Deck. While Steam Big Picture Mode streams the UI perfectly, launching any game results in a black screen on the client.

Expected: The game's visual output should be encoded and transmitted to the Steam Deck. Actual: Only audio and input (mouse/controller) are transmitted. The screen remains black. This occurs despite UFW ports being open and other PipeWire-based tools (OBS) working correctly. This suggests a specific failure in how the game's render buffer is captured under Wayland.

Steps for reproducing this issue:
Launch Steam on CachyOS (KDE Wayland session).

Connect from Steam Deck via SteamLink/Remote Play or Moonlight/Sunshine.

Start any game (Windowed or Fullscreen).

Observe that audio plays and inputs work, but the video feed is blank/black.
