I’m trying to display a fullscreen image in GLMakie, but it isn’t working. I’m running the following code:

```julia
using GLMakie
GLMakie.activate!(decorated=false, fullscreen=true)

w, h = 2560, 1080 # my monitor's resolution
img = rand(UInt8, w, h)

fig = Figure(size=(w, h), figure_padding=0)
ax = Axis(fig[1, 1], aspect=DataAspect())
hidedecorations!(ax)
heatmap!(ax, img, colormap=:greys)
fig

```

The `fullscreen` keyword has simply no effect. Is it a bug or am I doing something wrong?

The output from `versioninfo()` is

```julia

Thanks in advance for any help!

Could you open that as an issue? From a brief look in the source, looks to me like the `fullscreen` setting is not really used
