As a fellow Godot programmer I have to inform you that the latest AMD pro drivers have broken Vulkan Godot support. See issue: Graphical mess on newest AMD driver (25.8.1), on VULKAN, works on 25.6.1 · Issue #109679 · godotengine/godot
Your game displays garbled graphics like the ones in the post above on my system due to this issue.
This issue can be fixed by going in Godot to project settings -> rendering -> driver
Change the rendering mode from vulkan to d3d12.
