My guess is that incosolata does not have all the graphics characters,
so emacs drops to a different font when displaying them. For some reason
it is now dropping to some other different font and the display is
getting messed up.

I think what-cursor-position called with a prefix argument (so C-u M-x
what-cursor-position) tells you (amongst other things) the font under
the cursor.  For me, when using incosalata as default font,  the quarter
circles and arrow heads are in some different font.

I don't know what the fix would be if this is the problem but lets see
if it the problem first!

Best wishes
