Hide UI (U hotkey) doesn't actually hide the entire on‑screen UI

• Game Version: 20251222.9501.W

• Platform: Steam windows

• Mods: removed

• Hardware Specifications & Operating System:
  OS Version: Windows 11 22631.6060
  CPU: AMD Ryzen 9 7945HX
  GPU: RTX 4080 Mobile
  RAM: 32 GB DDR5
  Storage: NVMe 2TB

• Steps to Reproduce:

1. Press U hotkey.
2. While the HUD and 2D space UI, including the old-new Cat’s Eye, are hidden, the 3D space icons for joint/group actions, the photo spot, the bus spot, etc. still remain visible on the screen.
   (as I understand it, the problem is specifically with scalable sprites in 3D space).
