Color Banding in Game Mode HDR
I am using Bazzite on my HTPC (-deck image, Radeon RX 7900XTX). When using HDR in Game Mode, significant color banding is visible, which is not present when using HDR on my Steam Deck, or when using HDR in Gamescope on KDE in desktop mode. The banding seems to go away when the developer setting "Disable Color Management" is enabled, which makes SDR content appear extremely dark, but makes HDR content look correct.
Color banding is most obvious in the sky and clouds in The Witcher 3 and Death Stranding. Unfortunately the issue doesn't show up in steam screenshots or in-game screenshots, so here are smartphone pictures comparing Color Management being enabled vs disabled in The Witcher 3.
Has anyone else experienced this issue? Can anyone point me to any relevant github issues or forum threads that may be relevant? Thank you very much!

Solution
It’s an issue with the HDR patch used in that kernel, I think it should be fixed in an upcoming or newer build
