This affects Blender and in certain scripts vapoursynth (e.g. nnedi3cl and placebo in the same script).

This is due to ROCm (for OpenCL) using a different (major) LLVM version than mesa (for OpenGL).

The recommended workaround (compiling mesa with llvmPackages_rocm) did not work (compiling mesa fails, presumably because there are incompatibilities between the llvm versions), though I did not try very hard to get it to work.

Those issues explain this in more detail:

Probably this is getting worked on by danieldk: https://discourse.nixos.org/t/what-are-your-goals-for-21-05/11559/3 🥳
Update: ROCm doesn’t support GUI (though they say they still support OpenCL with gui?): https://github.com/NixOS/nixpkgs/issues/97401#issuecomment-789516544
