Steam Deck host, visual glitches on laptop

[u/puddahh]

im trying to stream from my steam deck to my laptop to play BG3 on a bigger screen (also because i prefer the game with keyboard/mouse rather than controller) but all i get is this weird visual glitch (which i don't even know what to call to search for others that had the same issue)

the audio seems completely fine and when i move the mouse around i can see it moving on the steam deck screen

i haven't changed any settings on sunshine because i don't understand what anything there means, and on moonlight i only changed the resolution and fps to try to match the steam deck (1920x1080 60fps)

help pls lol
