Hmm, kinda sounds like maybe your widget isn't drawing a background.
Possibly fltk's fl_bitmap() is not doing an 'or' so much as it's
only drawing the pixels that are 'set', so that one has the choice
to draw over an existing image.
Try drawing an fl_rectf() just before your call to fl_bitmap()
using the background color you want.
Or, don't do that and just make sure the widget you're deriving
from has a solid box() type type of some kind, like box(FL_FLAT_BOX).
This way when the widget redraws, it won't leave the old image behind.
