Running standalone Dolphin in 640x480 results in pixel perfect 1x scaling in games like Gradius ReBirth for example. Running it in 640x480 in the libretro core results in missing lines and scaling artifacts. The core indicates 640x528 to be the correct resolution, but running the game in 640x528 also results in incorrect scaling and artifacts.
