When casting from a Quest 3 to a PC, the passthrough video feed is not visible in the casting window, instead displaying a black screen. However, the passthrough video feed is visible in the Quest 3 headset. The issue only affects the passthrough feed, as other content displayed in the headset, such as the UI, are visible in the PC casting window. This issue occurs when the passthrough is enabled, and the casting window on the PC shows a black background, similar to when passthrough is disabled.
