Would this by any chance be in a mode-X resolution?

If so, you are either using an old version of Allegro, which had a bug with
solid text backgrounds in mode-X (upgrade to v2.2), or you are using a
customised proportional font (just yesterday I found a bug with regard to
solid text backgrounds with proportional fonts in mode-X :-)  If this is
the case, edit modex.c and in the _x_draw_character() function, replace:

   for (c1=0; c1<sprite->h; c1++)
      for (c2=0; c2<sprite->w; c2++)
         if (sprite->line[c1][c2])
            if (sprite->line[c1][c2])
               x_write(bmp, x+c2, y+c1, color);
            else
               if (_textmode >= 0)
                  x_write(bmp, x+c2, y+c1, _textmode);

with:

   for (c1=0; c1<sprite->h; c1++)
      for (c2=0; c2<sprite->w; c2++)
         if (sprite->line[c1][c2])
            x_write(bmp, x+c2, y+c1, color);
         else
            if (_textmode >= 0)
               x_write(bmp, x+c2, y+c1, _textmode);


If that isn't it, I'm baffled: try to isolate a fragment of code that
demonstrates the trouble and I'll see what I can do...
