Platform: Windows x64
Client version: 2.55.1.100

Issue:
Vehicle top texture (e.g., turret roof) disappears when moving on winter maps, but only in DX12 mode.

Steps to reproduce:

  1. Set graphics API to DirectX 12.
  2. Enter any winter/snow map.
  3. Move the vehicle.

Observed behavior:

  • Top texture vanishes as soon as the vehicle moves.
  • Texture briefly reappears for a split second when firing the gun.

Expected behavior:
Top texture should remain visible at all times.

Additional info:

  • Only happens in DX12 mode (DX11 works fine).
  • Only on winter maps (summer/desert maps are fine).
  • AMD graphics card.
