Yes, you read it right, I have an issue with PDF output when using TLatex (NOT TMathText!)
On the canvas in my Aqua window, I can see subscripts in my TLegend produced with TLatex. They look fine (attached file theory_h_p3.pdf, from a screen capture). When I save the canvas to a pdf file, now there is an ugly large space between the letters and the subscript (attached file theory_p3.pdf).
In the same script, I produce some other plots and they do not have this problem. The only difference between those plots and this “p3” plot that I can see is the text size and a few other minor details. The script is also attached (theory_h.C), and the function responsible for plotting is called “graph_p3”.
Any ideas what might be causing this?
