Describe the Bug

Having the Sunshine service running causes other applications such as Chiaki4Deck to end up with washed out HDR colors. Stopping Sunshine remedies the problem completely.

Expected Behavior

Sunshine not interfering with other applications.

Additional Context

I've been long since trying to figure out why HDR wouldn't display correctly when using Chiaki4Deck to stream my PS5 to my Windows PC and the developer of that application was trying to help me fix it too to no avail. Another user, also with an Nvidia card and Sunshine installed, eventually found out that stopping Sunshine fixes the problem. I tested it on my end and can confirm that the same is true for me. Starting Sunshine again immediately recreates the problem. The problem can also be seen when playing some HDR videos with the mpv video player in certain configurations.

Can you try changing the "Present OpenGL/Vulkan on top of DXGI" option to Disabled on the NVENC Encoder tab?

If it fixes the issue, then we have either a Nvidia driver or Windows bug affecting the Vulkan on DXGI presentation path.
