@juliosanz I think this is the reason for me suddenly seeing only a quarter of my screen; I run the git version of sunshine and with this commit in, I only see the left-upper quarter of the screen (I'm using Arch Linux + Wayland on both client and server, Moonlight current-git to connect)

Update: confirmed, went back to commit b0bf510 and scaling works normally again - I created #4599 to track it.
