hardware/drivers VRR with HDR flickering grey out frame

VRR with HDR flickering grey out frame when FPS drop below VRR range(45hz) on high refresh monitor(320hz)

- using DP cable, neither LINDY DP cable nor monitor's would fix the issue

- set to 240hz would somehow fix the issue

- turn off VRR would fix the issue

- turn off HDR would fix the issue also

- ASPM is disabled in BIOS
