If the example code is small and compilable, paste it here.
If it's large, try to reduce it.
Typically weird drawing behavior can be caused by:

An example of bad grouping might be:
grp = Fl_Group(100,100,100,100);
but = new Fl_Button(10,10,100,100); // BAD: button outside
the parent's xywh
grp->end();
