First, let me say thanks for getting ReShade 3.0.5 working with Cemu. I works great for all 8 games I've tested so far! Except one: ZWWHD
Using Cemu 1.6.3 to test Legend of Zelda Wind Waker HD with Reshade 3.0.5:
1. If you go to fullscreen *after* the 2D splash screen: the image will be a black screen, and maintain that black screen when Reshade is toggled to ON.
2. If you go to fullscreen *during* the 2D splashscreen before the game starts to render 3D, Reshade will load and work properly during the 2D splash screen, but when the game moves on to render 3D: the image will be the first frame of the 3D render, and maintain that frame when Reshade is toggled to ON.
3. Reshade works normal/great in window mode.
During troubleshooting: Activating any one or multiple of shaders will cause this to happen.
