Red Alert 2 Windows 8 DirectDraw compatibility

[XTF]

I'm stuck on this one.. Any hints?

The game Red Alert 2 runs on Windows 8, but as soon as I inject a DLL (via ddraw.dll or an extra DLL) it stops drawing buttons on the main menu. With the DLL it still work fine in windowed mode and it still works fine on Windows 7. The DLL is basically just

Code:

typedef HRESULT(WINAPI* LPDIRECTDRAWCREATE)(GUID*, LPDIRECTDRAW*, IUnknown*);
HMODULE dd_dll = LoadLibrary("system32/ddraw.dll");
LPDIRECTDRAWCREATE dd_create = reinterpret_cast<LPDIRECTDRAWCREATE>(GetProcAddress(dd_dll, "DirectDrawCreate"));
return dd_create(lpGUID, lplpDD, pUnkOuter);

I'm guessing some kind of automatic compatibility mode is activated for the original game that gets disabled by the DLL, but how do I find out what's causing this? It's important as the DLL provides improvements for gamers that should also be available on Windows 8 (and beyond).
