enum class is treated as int under gcc/clang

[ShaderManager]

https://godbolt.org/z/VZUd--

fmtlib v6.0.0:
fmtlib under clang/gcc formats enum class as int when there is no overloaded operator << for this type. MSVC emits error don't know how to format the type
fmtlib v5.3.0:
all major compilers (clang, gcc, msvc) emit error don't know how to format the type

Is there some regression between v5.3.0 and v6.0.0 related to this issue?

Good catch. Looks like regression was introduced in #1286. A cast should be replaced with an implicit conversion.

Should be fixed in 9a37d5f.

Looks like there was a regression.

The regression has been fixed in fd62fba.
