Comment 3 for bug 597633

Using the "Stellarium (no OpenGL2)" option forces the use of a difference font (Verdana) in place of the default font (DejaVu Sans). For your case, it seems the font itself is the problem (you're not alone with that).

A fix is in the pipelines but, in the mean time, just run the "Stellarium (no OpenGL2)" option (it makes no difference otherwise, and your system doesn't support OpenGL2 regardless).
