I am fairly certain Preview 3 or 4 didn't show this warning, but as far as I can see, it doesn't cause any run-time problems since I am using Metal.

Steps to Reproduce

Compile any Avalonia application with <TrimMode>full</TrimMode> and <UseMonoRuntime>true</UseMonoRuntime>, I suppose.

Did you find any workaround?

No response

Yes, this warning is new. I'll downgrade it into a log message instead of a warning.

Ah, so there was no behavioral change (Avalonia doesn't need to adjust), you only started emitting a warning for an existing behavior?

Yes, that's correct.
