(bug?) -spread produces different result in IM6.3.9.10

[kyle1234]

Hi all,
I noticed -spread option produces different result between IM6.3.9.10 and IM6.3.8.5.
when I executed command below in IM6.3.9.10, convert.exe produces unexpeced black noises.(in IM6.3.8.5, it produces correct result without black noises.)
convert.exe -size 200x200 xc:white -fill blue -draw "rectangle 20,10 179,189" -spread 1 test.png
best regards,
Kyle
