I'm surprised you even have Vulkan support on the Windows driver of that GCN 1.0 GPU…

Occurs on Windows 10 with RX 580 when MSAA is set to 4x and above. Tested on Godot 4.0, 4.0.2 and 4.0.3-rc2 (with C# support for each of these).

They've actually mentioned GLES3, not Vulkan:

Though, I wasn't able to replicate it with compatibility/mobile renderers on GCN4 card (specifically re-tested on v4.0.beta13.mono.official [caacade56]):

And while on GCN4 GPU it only happens with MSAA 4x/8x enabled, they also definitely have it completely turned off here.

SSIL isn't available when using the Mobile and Compatibility rendering methods. The Environment property does nothing when not using Forward+.
