Hello there,
I have a Steam Deck LCD model. I'm trying to use Remote Play to stream from my Windows computer to my Deck, but I've encountered two different issues depending on the decoding method:

• Hardware decoding: Provides correct color accuracy, but there is jittering/stuttering.
  
• Software decoding: Everything runs smoothly, but the colors and contrast are washed out.

I haven't seen this issue mentioned anywhere except for this Reddit post , which illustrates the issue better than I can.

About a month or so ago, software decoding didn't have this kind of issue (or at least, I don't remember it being this noticeable).

I have also tried the Sunshine + Moonlight alternative. While it fixes the color and stuttering issues, it also introduces compression artifacts and color banding everywhere. I spent hours trying to fix this without any improvement, so Moonlight is not a viable alternative for me.

EDIT: Further testing and searching for alternatives led me to the Steam Link app in the Discovery store. The app provides correct color accuracy, doesn't stutter or jitter, and doesn't have any banding or compression artifacts, regardless of hardware or software decoding.
I'm going to use Steam Link for now, but it's kind of weird that the app works perfectly while the Steam Client has these issues.
