[BUG] GR error with Latex strings, pyplot crash.

[pcjentsch]

This might be two different bugs, but they all appeared at roughly the same time.

First, GR gives plotting errors when using strings with latex in them.

julia> using Plots
julia> plot([1,2],title = "test \$\\alpha\$")       
GKS: Rectangle definition is invalid in routine SET_VIEWPORT

The following crashes the REPL, it appeared after I installed StatsPlots, but has persisted with a reinstall of Plots and removal of StatsPlots.

julia> using Plots
julia> pyplot()
Plots.PyPlotBackend()
julia> plot([1,1])

VScode outputs

The terminal process terminated with exit code: 3221225477

I can't reproduce the PyPlot crash in the REPL, so might be an iteraction with VSCode
