Hi,

I use (GL)Makie for animations. When I replace `using GLMakie` with `using WGLMakie` its fails:

```julia
 ERROR: type GenericIOBuffer has no field io

```

Is it possible to display animations via WGLMakie ? Is there an example available ?

Thank you for your help.  
Laurent

I think I fixed that in the most recent release. In general, it helps a ton, if you can post a small example to reproduce the error

Hi Simon,

thank you very much for your reply. I apologize for the missing MWE: I though that the answer might have been that this feature was not covered by WGLMakie.

Here is the MWE :

```julia
using WGLMakie # OK with GLMakie

function test(n,nh)
    scene = Scene()
    x = [(i-1)*2π/(n-1) for i in 1:n]
    y = sin.(x)
    xn = Node(y)

    scatter!(scene,lift(x -> x , xn),markersize=5,color = :red)
    lines!(scene,lift(x -> x , xn),color = :blue)

    record(scene, "output.mp4", 1:nh) do j
        y .= sin.(x .+ 2π*j/nh) 
        xn[] = y 
    end
end

test(100,100)

```

BTW, is there a simple way to skip the movie generation and only enjoy the animation ?

Yes, just replace record with this:

```julia
display(scene)
foreach(1:nh) do j
        y .= sin.(x .+ 2π*j/nh) 
        xn[] = y
       yield()
end
```

Ach, `yield()` of course.  
Thank you very much again !

When you mention the _latest version_, does this mean that my MWE should work with it ? I think that I use the latest release and I obtain an error…

The “live” display is OK with, `display`,`yield` and `WGLMakie`.  
Thank you again !
