[dxvk] Starcraft II bright squares

[Blisto91]

In at least one specific Starcraft II map (likely more) when running with dxvk and amdvlk (or the Windows driver) a bright square can be seen appearing in the top left corner when moving the camera to a specific area. Issue does not show with RADV or Nvidia.
The map shown below is "Void Thrashing".

This has been tested on a RX 7900 xtx with 2024.Q2.1 and 2024.Q2.2. Use dxvk master to avoid GPL hang issues.
