Steam Deck - Low FPS Stream

[Hiro]

Posting this problem here in case someone has a better workaround (or a solution).

When streaming from PC to Steam Deck after sometime (and only sometimes) the stream lower the FPS (feels like 10 / 15 fps).
It is just the stream, the game is running fine on the Host PC.
It happens "randomly", may be at the start, after 5 minutes, after 1 hour or never happen.

I use mostly Linux nowadays, but have Windows for games that refuse to be good.
The issue happen on both hosts:
- Windows 10 (Steam stable / beta)
- Pop!_OS 22.04 (Flatpak Steam, also stable / beta)

Already tried to disable hardware encoding but the problem seems to becomes more frequent (could be bias, the point is it does not help).

Workaround I have found:

Resize the game window.
- Games in Full screen: Changing the resolution.

- Games in Windowed mode: Change the window size.
Example: Yuzu - Press F11 twice.

For some reason, doing this make the stream full-speed again (most of the time).
