What happened?

When using any shaders with Iris, screens from Lifts mod turn black and their contents move to the bottom left corner in a plain text form.

This is caused by Iris getting confused when Lifts renders to a custom render target. I'll look into getting some sort of API added to allow mods to tell Iris to not mess with their rendering when they're rendering to custom render targets.

I have implemented some code locally that can fix this issue entirely on Iris's side, but it will be some time before I am able to finalize it and push it to GitHub.

Note: This needs to be ported over to 1.17+, currently the fix is only on 1.16.5.
