GLMakie with blocking thread

This works on my PC, could it be, that you only run julia with one thread?
Make sure Threads.nthreads() > 1.
If there’s only one thread, you will need a yield to allow any other task to work.
Also, be aware that GLMakie isn’t threadsafe, so you can’t just update any plot from another thread!
You will need to push the updates to a channel, or something like that:

function mwe()
   channel = Channel(Inf) do channel
       fig = GLMakie.Figure()
       gl = fig[1, 1] = GridLayout()
       ax = Axis(gl[2, 1])
       t = Toggle(gl[1, 1], active=false, tellwidth=false)
       splot = scatter!(ax, rand(Point2f, 10))
       display(fig)
       task = @async for update! in channel 
           update!(splot) # pass Makie objects in here
       end
       wait(task)
   end
       
   Threads.@spawn begin
       while true 
           push!(channel, (plot)-> begin 
               plot[1] = rand(Point2f, 10)
           end)
           sleep(1/25)
       end
   end
end
