iOS - UMG widgets render errors on Metal with Scroll Box

Hi,

Sorry it took so long. But this issue will be fixed in 4.17. In earlier releases you can apply simple code change to fix it.

In MetalRHIPrivate.h file find

#define BUFFER_DYNAMIC_REALLOC BUF_Volatile 

and replace it with

#define BUFFER_DYNAMIC_REALLOC BUF_AnyDynamic
