ehhh... I forgot to tell you how I did workaround for this bug... It's simple:
I created temporary bitmap and rastport with layer and layerinfo (it could be
done either in OM_NEW and GM_RENDER - you should check if size of visible area
of gadget was changed - be _very_ careful while calculating size, you must
support right/bottom relative tags/flags as well, especjally when you're
writing gadgets that will be placed in SYS:Classes/Gadgets/ as I did), and
gadget renders graphics to this rastport, then bitmap is blitted to
msg->gpr_RPort. It needs more memory but it looks better (you don't see how
lines appears on screen ;).
