Hey there I am struggling with these issue. There's like a strobing effect on my left eye. If I close my left eye its fine. I've tried disabling instanced stereo and mobile multi view with no luck. I'm just running the demo scene with no changes. Any suggestions? I tried 5.3 and 5.5.4. I am working on meta quest 3

    I also made sure to turn of Lumen and Nanite. Still the same result.

    One detail that isn't quite visible in the video above is the the flashing region shows the perspective of a static camera that isn't tied to my head movement.

    I’ve also tried disabling spectator mode and removing the spectator camera from the be template to see if it had anything to with it. No luck

    I’m disabling spectator screen in a post engine callback in my game cop module. I think there’s a static function to just set the spectator screen mode directly

    I though this was caused by spectator screen somehow. However the following additions didn't help.

    ```

    #include "MyGame/MyGamePlayerController.h"
    #include "HAL/IConsoleManager.h" // Make sure to include this header
    #include "HeadMountedDisplayTypes.h"
    #include "HeadMountedDisplayFunctionLibrary.h"
    #include "IXRTrackingSystem.h"
    #include "IHeadMountedDisplay.h"
    #include "ISpectatorScreenController.h"
    #include "DefaultSpectatorScreenController.h"
     
    #include "Misc/CoreDelegates.h"
     
    void AMyGamePlayerController::BeginPlay()
    {
        Super::BeginPlay();
        // Now that the controller is active, the XR system should be fully initialized.
        UHeadMountedDisplayFunctionLibrary::SetSpectatorScreenMode(ESpectatorScreenMode::Disabled);
     
        if (auto System = GEngine->XRSystem)
        {
            if (auto HMD = System->GetHMDDevice())
            {
                if (auto Controller = static_cast<FDefaultSpectatorScreenController*>(HMD->GetSpectatorScreenController()))
                {
                    UHeadMountedDisplayFunctionLibrary::SetSpectatorScreenMode(ESpectatorScreenMode::Disabled);
                    // Schedule the update to run on the render thread.
                    ENQUEUE_RENDER_COMMAND(FUpdateSpectatorScreenMode)(
                        [Controller](FRHICommandListImmediate& RHICmdList)
                        {
                            Controller->UpdateSpectatorScreenMode_RenderThread();
                        }
                        );
                    UE_LOG(LogTemp, Warning, TEXT("SpectatorScreenMode forced to 0"));
                    return;
                }
                UE_LOG(LogTemp, Warning, TEXT("Failed to retrieve spectator screen controller"));
                return;
            }
     
            UE_LOG(LogTemp, Warning, TEXT("Failed to retrieve spectator screen hmd"));
            return;
        }
        UE_LOG(LogTemp, Warning, TEXT("Failed to retrieve spectator system"));
    }

    ```
