Hi. I've encountered nasty bug with labels. I've tried to figure out how to
reproduce it for quite long time. So:
I have this little example: window with several widgets(see screenshots).
Pressing on "click me" button will take value from text input widget(upper
one) and set it as label for text output widget. This cause very often that
label of input text widget(unrelated one) becomes "dirty" (see screenshots)
I already know that actually I have to call function to redraw parent
window, because I'm changing external label, and everything would seem
fine, but this will just hide this bug. Because it occurs to me in some
other cases: hide/show of another window(currently I'm trying to figure
out how to reproduce it more or less constantly). Sometime even inner
labels(e.g. button's label) becomes dirty.
If I use fltk without xft support everything is fine.
