XWayland games locked at abnormally low fps with VSync enabled

[smithyyang]

games running via Steam/Proton under XWayland are locked under the monitor refresh rate when VSync is enabled in-game whether the vrr is on. On a 165Hz display, this results in 40-50 fps. And On a 60Hz display, this results in approximately 30 fps.Disabling VSync restores normal framerate but causes screen tearing,leading to serious stutter
This is confirmed to be a Hyprland regression. The same games run perfectly fine under KDE Plasma Wayland with no fps locking issues.

Affected games:
Sherlock Holmes Chapter One (via Proton)
Assassin's Creed (via Proton)

Steam launch options:
gamemoderun mangohud prime-run %command%

I use basically the exact same setup, differing only in the monitor (still on a 144 Hz @ 1920x1080). I have found that disabling VSync in all games, then using MangoHud to handle the max FPS (mainly to reduce GPU load) works the best. I have (2) settings, one for 60 FPS (turn-based games) and 144 FPS (for everything else).

Bro Use X11 instead Which is way much better in Gaming than Wayland
