Game "Deadcore" missing font texture, and poor quality textures in game.

A native 32-bit Unity based game "Deadcore" ( https://store.steampowered.com/app/284460/DeadCore/ ) shows missing textures and fonts in menus, and in game textures are very low resolution.

AMD Radeon R9 Fury X (FIJI, GFX8)

I think this is because of misreported VRAM or something, and game shrinks them to almost 1x1 pixel.

Log file (~/.config/unity3d/5 Bits Games/DeadCore/Player.log) from the game confirms this: Player.log

The issue of memory reporting, also showed up in some other places before with zink, i.e. Serious Sam 3, can't detect VRAM. Also I believe Unigine Superposition thinks it is 256MB, etc. Which all could be due to a fallback and lack of GL_ATI_meminfo and GL_NVX_gpu_memory_info emulation / faking.
