      Description

      The text rendered in TLatex (e.g. in a histogram title) has alignment problems for subscripts.

      Below is an example to reproduce the issue that results in the output attached, where the "XX" subscript have different baselines:

      TCanvas* c1 = new TCanvas("c1", "c1");
      TH1D* h = new TH1D("h", ";#mu = A_

      {XX}^{YY} / A_{XX}

      ^

      {YY};-2#Deltaln(L)", 100, 0, 1);
      h->Draw();

      The behaviour changes depending on the string used, for example everything is correctly aligned if the title is simply "A_{XX}^{YY}

      / A_

      {XX}^{YY}", so it looks like it depends on the presence of other math symbols in the string.

      The only workaround I found at the moment is to use "#scale[1]{#mu} = A_{XX}

      ^

      {YY} / A_{XX}^{YY}

      " that gives the correctly aligned output.
