Needing Help With Ishiiruka and Vulkan Shaders

[Joom]

I'm hoping somebody here is able to elaborate on this, because I can't for the life of me figure it out. I'm attempting to use shaders with Ishiiruka and Vulkan as my backend, but I always get an error message stating "Failed to get pipeline for backend shader draw" upon loading a game. They work just fine in vanilla Dolphin, so I'm not sure what's going on. Googling the error leads to a short lived conversation on the official development thread on the Dolphin forums, but a solution was never posted.
