Comment (by X512):

 Reason of this bug is WonderBrush shift scrolled contents with CopyBits
 and scrollbars area is included to shifting. Before transparent views
 supports children views were clipped but after transparent views were
 introduced they are not clipped if view color is B_TRANSPARENT_COLOR.
 BeBook don't says about should be children views clipped in CopyBits or
 not so WonderBrush seems cause undefined behavior.
