VRR with explicit sync freezes after resume from suspend

Activating VRR with explicit sync after suspend-resume freezes the system.
Steps to reproduce:

  1. have a wayland compositor with enabled VRR and explicit sync (tested with kwin vrr always on and hyprland vrr=1)
  2. boot and login in text mode
  3. systemctl suspend
  4. resume
  5. start wayland compositor

Same results with suspend-resume while the compositor is running. Works fine with disabled explicit sync or vrr.
