Hi,

I wonder what is the expected speed of WGLMakie compared to GLMakie. The following MWE takes 20s with WGLMakie compared to 0.8s using GLMakie.  
Is is expected ? Could someone explain the difference ?

> **MWE**
>
> ```julia
> using GLMakie,AbstractPlotting
> function MWE()
> scene = Scene()
> nh=50
> nx=200
> ny=200
> xs = LinRange(0, 10.0, nx)
> ys = LinRange(0, 15.0, ny)
> 
> zs=zeros(nx,ny)
> 
> function updatezs!(t)
> for j in eachindex(ys)
> for i in eachindex(xs)
> zs[i,j] = cos(xs[i]+t) * sin(ys[j]+2t)
> end
> end
> end
> 
> zn = Node(zs)
> # heatmap!(scene,xs,ys,lift(z->z,zn),camera = cam2d!)
> surface!(scene,xs, ys, lift(z->z,zn),camera = cam3d!)
> display(scene)
> t=0
> for j in 1:nh
> t+=0.1
> updatezs!(t)
> sleep(0.01)
> zn[] = zs 
> yield()
> end
> end

In addition, the GLMakie plots are prettier…
