WIIScrubber edited ISO, only replaces music and intro video. Works fine on Dolphin and real Wii.

What's the problem? Describe what went wrong.

This problem is evident when "Compile shaders before starting" is enabled. On D3D11, there is no shader compilation progress bar during game startup after initial shader compilation. On D3D12, it seems the shaders are recompiled every startup. This can waste a lot of time when testing games that involve many shaders.

What steps will reproduce the problem?

1. Enable "Compile shaders before starting"
2. Load a game that will involve many shaders (Super Smash Bros. Brawl through Gecko OS works for me)
3. Complete initial shader compilation
4. Exit and restart emulation
5. Compare D3D11 vs D3D12 results. Shaders will recompile on D3D12 during every game startup. D3D11 shader recompilation is much faster.
