It's not entirely random. What I have noticed is that one or more vertices are corrupt. Sometimes you see the correct content but skewed, which is what happens if you just move one of the vertices (its texture coordinates). With two or more distorted coordinates, we can be sampling from anywhere within the texture - which can mean that we see the wrong glyph or a highly distorted composite of several glyphs (since all the active glyphs are stored in a single texture).
