Ok, but I'm using foreground/background attributes:

<span face=\"sans-serif\" weight=\"bold\"  background=\"#0a3b6e\" 
foreground=\"white\"><i>Connecting server...</i></span>

and in this case - it does draw background.

I made 2 pictures, one with what I have now 
(http://adamk.rootnode.pl/example-bad.png 1.9KB size) and second with 
what I want to achieve (http://adamk.rootnode.pl/example-ok.png 1.9KB 
size). Note, that my markup may be much more complicated with few 
background colors, so drawing 2 boxes above and under text rendered by 
pango in background color is not possible (there may be few colors). I 
could analyse pixmap after drawing text, but I'd like to avoid it.
