Similar situation

Have you found any solution yet?

Interestingly, it renders completely correctly in Linux under Wine

The rendering mode is unsupported by Vulkan.

Check the shader if it’s open to checking. Likely the volume needs an sm5 switch or similar to fall back on.

The problem is not only with the cloud shader. Any shadows look wrong. Including basic object shading.

And as I said above, this problem only occurs in native Windows. It doesn’t happen under Wine or natively on Linux

Because linuxes uses what?

If you still don’t understand I’ll say it again differently:

The Windows build is not actually using Vulkan correctly. Be it a switch in a material, an issue with your build, or the engine itself having a bug.

Also, Package for release and test that. On Linux as well. Pie is not a reliable way to tell what works or doesn’t.
