So, I'm on Kubuntu 20.04, probably on the latest version of steam (I'm on the steam beta update actually) running on a ryzen 7 5700g.

Also did the Steam link installation on my raspberry pi 4 (4gb ram) TODAY, so I'm running the lastest version as of 18/aug 15h gmt-3 at the very least.

I searched for this and it was recommended to turn off hardware acceleration on the remote play advanced settings area. So I did that - It did fix one other game I was having issues with, but SRB2 Kart didn't work still.

It starts normally, but as soon as it stops to load stuff, I get a "bad network" icon and the video just stops completely. I still get audio in the background but no input goes through and no image updates either.
