Thanks for reporting this. It's an odd issue!
I could reproduce it using SDDM (which uses X by "default").
Just to close the loop on it, it's been reverted for other reasons:
https://gitlab.freedesktop.org/drm/misc/kernel/-/commit/717b432b6d55e1dcefcb5e2ec315bf66b6ab8c54
When something comes back in a different form I'll double check X again too.
