The maximum resolution for recording seems to be bounded by the size of my screen.

```julia
GLMakie.activate!()
grid = zeros(2000, 2000)
fig = Figure(resolution=(2000, 2000))
ax = Axis(fig[1, 1], aspect=DataAspect())
hm = heatmap!(ax, grid)
record(fig, "renderlines.mp4", 1:500; framerate=30) do i
    grid[1:10:2000, i] .= 1
    grid[i, 1:10:2000] .= 1
    hm[3][] = grid
end

```

The preceding code yields:

 ![glmakie_lines](https://global.discourse-cdn.com/julialang/original/3X/1/7/1741e1072e36acd16ede6306468a144727aac140.png)  
Not all lines are displayed but they appear when we zoom in the GLMakie interactive window.

The recording inherits the resolution imposed by the screen (image 1). Is there a way to increase the resolution to see all lines clearly ?
