VRR and FPS not aligned with HDR on

[rubberduck-ninja]

Hyprland version

Hyprland 0.52.1 built from branch v0.52.1 at commit 967c3c7 clean (version: bump to 0.52.1).

In case it matters, I am on CachyOS, so arch, btw

Regression

Not a regression, AFAIK

Describe the bug

My VRR framerate caps out at ~80hz on one monitor only when HDR is enabled. It is an LG 120hz. I have an AMD gpu if that matters. My Ultrawide 1440p monitor works fine

I have an AMD GPU and an AMD CPU with an integrated GPU. I don't think it is a dual GPU issue, but I thought I should mention it

Reproduction steps

1. Have a 4k 120hz TV with VRR and HDR (lol)
2. On that monitor, set: cm, hdr, vrr, 2
3. xx_color_management_v4 = true
4. Run a VRR app (I used https://github.com/Nixola/VRRTest but FFXIV has the same behavior. Gamescope also had the same issue)
5. For my TV, I mash the green button on the remote to see my VRR info. It bounces between 70-80 if my FPS is above 80
6. Remove cm,hdr
7. VRR now matches the FPS up to 120hz

I have a DP to HDMI dongle, but the same effect happens over HDMI. I have tried various resolution. KDE and Sway both work fine, so I don't think it is hardware

Direct Scanout corrupts my screen with VRR applications, so I don't use it. Allow_tearing doesn't matter either way.

With HDR and VRR on, If I disable no_break_fs_vrr and no_hardware_cursors, my screen just refuses to take the signal at all. Not sure if that is related or not
