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

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...
