[Message part 1 (text/plain, inline)]

I do still believe it is a bug.

I changed the definition of to

(set-face-attribute 'fill-column-indicator nil :background nil 
:foreground "white" :stipple '(10 1 " \x0\x0\x0\x0\x0\x0"))

one blank representing a single set bit, followed by quite a few null 
string literals as I do not know what happens if I dynamically change 
font sizes. Does this influence the necessity to change the bitmap 
literal of a stipple?

Nonetheless, at Linux at scale level 0 a single line is shown, at some 
increases of the scale level  I see two or more lines, at higher scale 
levels just one again.

Also, display-line-numbers-mode influences the position of the stipples. 
Which IMHO shouldn't be the case.
