I suspect the glyph draws pixels outside of the character cell. Vim then
erases them when drawing another character. This has happened with some bold
fonts as well (there is special redrawing logic for that).
You can try moving the cursor in both directions over the character to see what
happens.

is to make it so complicated that there are no obvious deficiencies.
