I was plotting some curves with a lot of low level noise with  
GLMakie and the plots had a lot of extra line cruft as if the  
line segments for the lines in the plot were not being correctly  
handled.

![lines_artifacts_glmakie](https://global.discourse-cdn.com/julialang/original/3X/f/2/f2846949574fd702364ee45a0d62c0b26a609b69.png)

A MWE for the above example is

```julia
using GLMakie;
data = [1 + 2*rand() + i/100 for i in 1:10000];
lines(data)

```

This should show a line of slope 1/100 with random noise as  
a thickening strip of size 2 superimposed.

This is **much** less than the figure dimensions so the plot  
should resemble a thick line. I find that if I zoom in enough that  
some/most of the spilling line ends clean up.

Can anyone else reproduce the problem?

Could you open an issue? That looks like something in the line shader going haywire

I have opened an issue [Line plot artifacts with GLMakie](https://github.com/MakieOrg/Makie.jl/issues/3906).

A work around appears to be setting `joinstyle=:round`
