Makie examples not working on Linux

[Florian]

Running the makie-plot.jl example with the instructions given in #133 gives me the following output:

I am on Linux:

julia> versioninfo()

I did some rudimentary debugging with print statements.
What I found is that the render_function in the makie-plots.jl example is never triggered. The same happens with makie.jl and also gltriangle.jl.

Here are the other outputs for completeness:

• makie.jl

• gltriangle.jl (or is this the desired output? it seems a bit boring though ... 😅)

Also: I am seeing some WARNING: redefinition of constant warnings when using QML. Looks like this is triggered by Revise.jl, at least disabling it removed the warnings, but did not solve the initial problem.
