    Related: tdf#100925 background not getting set under X sometimes
    
    not sure why this is the case, but it is reminiscent of rhbz#1283420 which
    results in missing glyphs in some circumstances
    X11CairoTextRender::getCairoContext has a hack in it for that problem, whic
    forces a read from the underlying X Drawable before writing to it which seems
    to have the effect of syncing it up.
    
    So, just before drawing the bg, draw a glyph on it to get it synced, and then
    overwrite it.
