Jonas,
when the bitmap is drawn with transparency, the background at the time of
drawing is shown instead
of the designated transparency color. This is a once-off thing. It does not
automatically get
redrawn if the background is altered. 

What you have to do is recreate the button images whenever the background is
altered.
