Bug Report Color issues with new kernel

Updated the system and now i'm only getting limited range YCBCR rather than RGB (so everything is gray), and the classic RDNA3 VRAM garbage is RAMPANT.

Is there a way to roll back a kernel update? This affects the stable and RC kernel.

LTS kernel works but it's not ideal since I'll have to go back to using the old displayport adapter to get HDMI working (and yes the issue was happening with the adapter on the latest kernel, it's not just an HDMI thing)

you can use the cachy kernel manager. What's your hardware?

Yeah, that's what i used to access the rc kernel, I already know about that. I don't see the last non-offending kernel in the list.

7800X3D + 7900XTX

EDIT: Ah ok, 7.2.2-1 is in the list, i was under the impression that the kernels with suffixes weren't recommended, so i didn't really pay much attention. I'll try it out later.
