MWE?

It was happening for any plot yesterday so I switched to CairoMakie. Today I can't reproduce it. Following the code from the line it mentions https://github.com/JuliaPlots/Makie.jl/blob/master/WGLMakie/src/wglmakie.js#L65 I guess it tried to get a scene from the scene_cache but got undefined and it doesn't know how to handle that.

this is a mwe for me

using WGLMakie, DataFrames
WGLMakie.activate!()
categories = string.(1:9)
df = DataFrame(rand(100, 9), categories)
df2 = DataFrame(rand(100, 9), categories)

n = nrow(df)
for (i, f) in enumerate(categories)
    fig = Figure(resolution=(600, 400))
    ax = Axis(fig[1, 1], xticks=(1:length(categories), categories))
    a = fill(i, length(n))
    violin!(ax, a, df[:, f]; side=:left)
    violin!(ax, a, df2[:, f]; side=:right)
    display(fig)
end


fig = Figure(resolution=(600, 400))
ax = Axis(fig[1, 1], xticks=(1:length(categories), categories))
