gtk: gtk+-2.10.14
directfb : DirectFB-1.0.0 (with intel gdl as gfxdriver)
cairo:  cairo-1.4.2
pango: pango-1.16.2
cpu: intel Olo

I used gtk_label_set_label to change my label text in my  button click
callback,
but string(old one) not clear , so new one was over old one.
and I found that new one just cover old one if font width not change,
otherwise, old one could be show ether.

I have no ideal ,it's pango layout bugs or something else?
thanks for help
