Fixed the following issues introduced when VR Preview was upgraded to the VR Sync Player:
- Stuttering, audio/video desynchronization, and sluggish UI response when playing dual 8K OpenGate videos under extremely high load.
- VR scene freezing and the previous video’s LUT carrying over when switching videos.
- Interpolated frames not appearing in the headset when making half-frame adjustments with Ctrl + Left/Right Arrow.
- UI errors triggered by certain playback state changes.
Also fixed white blocks obscuring the preview in Log Curve Grade.
