GR.__init__ changes Environmental Variables
I took a look at GR.jl’s __init__ and I noticed it set some environmental variables:
julia> orgENV= copy(ENV);
julia> using GR
julia> setdiff(ENV,orgENV)
4-element Vector{Pair{String, String}}:
"GKS_ENCODING" => "utf8"
"GKS_FONTPATH" => "C:\\Users\\kittisopikulm\\.julia\\packages\\GR\\BwGt2\\src\\..\\deps\\gr"
"GKS_USE_CAIRO_PNG" => "true"
"GRDIR" => "C:\\Users\\kittisopikulm\\.julia\\packages\\GR\\BwGt2\\src\\..\\deps\\gr"
Setting environmental variable results in slowdown
julia> begin
ENV["GRDIR"] = "C:\\Users\\kittisopikulm\\.julia\\packages\\GR\\BwGt2\\src\\..\\deps\\gr"
ENV["GKS_FONTPATH"] = "C:\\Users\\kittisopikulm\\.julia\\packages\\GR\\BwGt2\\src\\..\\deps\\gr"
ENV["GKS_ENCODING"] = "utf8"
ENV["GKS_USE_CAIRO_PNG"] = "true"
end
"true"
julia> @time begin
@time using GR_jll
x = [0, 0.2, 0.4, 0.6, 0.8, 1.0]; y = [0.3, 0.5, 0.4, 0.2, 0.6, 0.7]
gr = :libgr
@time @ccall gr.gr_polyline(6::Cint, pointer(x)::Ptr{Float64}, pointer(y)::Ptr{Float64})::Nothing
@time @ccall gr.gr_axes(0.2::Float64, 0.2::Float64, 0::Float64, 0::Float64, 1::Cint, 1::Cint, (-0.01)::Float64)::Nothing
@time @ccall gr.gr_updatews()::Nothing
end
0.741127 seconds (292.18 k allocations: 19.435 MiB, 0.92% gc time, 0.46% compilation time)
2.322584 seconds (3.92 k allocations: 223.016 KiB, 0.46% compilation time)
0.012314 seconds (3.53 k allocations: 203.047 KiB, 99.16% compilation time)

3.149256 seconds (416.77 k allocations: 27.419 MiB, 0.22% gc time, 0.83% compilation time)
I actually get a blank plot at the end of this, but now it takes more than two seconds to call gr.gr_polyline.
Setting ENV[“GRDIR”] is sufficient to cause the slowdown

Setting other environmental variables does not result in a slowdown
