GKSQT problem, help needed to debug

General Usage
7

I believe to have the same issue with:

using Interact, Plots, Mux
mp = @manipulate throttle=.05 for λ=0:.1:5, μ=0:.1:5
    xs = range(0.0, 1.0, length = 100)
    Plots.plot(xs, x -> λ*x^2 + μ)
end
ui = dom"div"(mp)
WebIO.webio_serve(page("/", req -> ui), 8002)

Did you manage to have a workaround/solve ?
