During a remote play session, the mouse input from the client is seemingly sent to the host in a jumpy manner, rather than a smooth movement. This occurs when using my window manager, dwm, as well as steamos-compositor-plus. This makes it impossible to play many games. Both client and host are on Arch Linux. It isn't visible on the client, but you can see it in game from the camera movement and the host's monitor(s).

Steps for reproducing this issue:

1. Launch a remote play session for any game, with both linux host and client.
2. Move mouse.
3. It may be best to view this in a game with mouse camera controls.

(I know yis didn't want smooth locomotion, but I'd like it for my mouse :p)
