Host OS: Windows 11
Client OS: visionOS 27 Beta
Steam Link Version: Latest test flight / version (I think 1.3.31 Beta)

Steps to Reproduce:

1. Launch Steam Link natively on Apple Vision Pro and connect to the gaming PC.

2. Hold the back button on the controller to bring up the Steam Link menu and select the virtual keyboard

3. Press the virtual windows key

4. Move the cursor over the Windows Taskbar or open the Start Menu.

Expected Result:

The mouse cursor should remain visible and track properly over all Windows UI elements, including the taskbar and system menus.

Actual Result:

The mouse cursor completely disappears/hides when interacting with the Windows taskbar, the pop-up taskbar menu, or anytime it is not running directly on top of Steam's Big Picture Mode interface.
