Any clues on how to fix the fonts? It seems the font kerning is wrong. It happens both in graphics and in all sorts of text styles...
This happens with Mathematica system fonts but also with certain styles in graphics. Moreover, when I select with the mouse cursor the affected text, the selected text does jerky movements with glyphs moving on top of neighbouring glyphs.
