Missing fonts in plot - Linux
When ragg::agg_png is used to export the graphic and there is some symbol, it is not displayed. This does not happen with grDevices::png.

I find that sometimes the default symbol font on Linux is pretty bad and either lead to missing glyphs or wrong dimensioning when setting up expressions. I'll see if I can somehow improve the default behaviour but otherwise it might make sense to set up a different default symbol font on your machine using fontconfig
