Issues with Direct3D on dev build

[JosJuice]

This sounds like a known bug that affects all Wii games that started happening when 5.0-76 was merged. Other than not using Direct3D 11, the following workarounds should also work:

Not starting in fullscreen
Enabling Render to Main Window
Disabling Dual Core (I haven't confirmed this one)
