Hi, I’m not sure whether this is a Makie or a DSP problem, but here we go:

Looks like it is a problem with neither, but rather FFTA.jl and FFTW.jl conflicting ([see link](https://github.com/JuliaMath/FFTA.jl/issues/146)).

I would recommend uninstalling one of them if possible, since complications in selecting the right FFT backend is a known issue with AbstractFFTs.jl:

> <https://github.com/JuliaMath/FFTA.jl/pull/79>

> For now, just to demonstrate what it would take to drop \`AbstractFFTs\`, ref #77.… If we take this route, then we might want to consider other adjustments as discussed in #77. I think it will also make it easier to set up documentation for our methods.

If uninstalling is not an option, you can monkey-patch the shown signature of `plan_rfft` to use the correct backend.

My understanding is that KernelDensity in Makie uses FFTA and FFTW is in DSP.

Yeah, my bad. Looks like KernelDensity.jl [switched to FFTA in v0.6.11](https://github.com/JuliaStats/KernelDensity.jl/releases/tag/v0.6.11), so downgrading to v0.6.10 can solve the problem.

Do you know what version of Makie can I use then?

AFAIU Makie will be downgraded automatically when you `]add KernelDensity@v0.6.10`
