Iris 1.7 performance issues: SOLVED (by disabling debug mode)

I have an rx6800xt, ryzen 5600x, and am having dramatically lower performance when running with any shader on Iris 1.7 compared to previous versions. When running the base330 pack (basic pack from ShaderLabs discord) I get less than 100fps, whereas I got 300+fps on previous versions, and on both 1.7 and previous versions I get 1000+fps with no shaders in the same world.
