Hello!

The case seems to be resolved right now. And actually the opinion of a  
1 pt font size is wrong: the cursor's size is like with a 10 pt or 12  
pt font size. The effect might be better described like two  
differently scaled glyph masks put on top of the other. Since they  
don't match completely, some light (or black) can pass through them  
onto the screen.

Anyway, the cause seems to be that I am using fontsets built with an  
elder and invalid (?) syntax like here

    (create-fontset-from-fontset-spec "-b&h-lucidatypewriter-medium-r- 
*-*-10-*-*-*-*-*-fontset-10pt_lucida_sans_typewriter" t 'noerror)

When I don't use these fontsets the other X server does render the  
fonts correctly (the default server does not seem to have problems  
with this).


I think, it can be closed as resolved/self-produced...
