Yes, but because it's so slow I use it less than once a month.

It feels like it takes half an hour or so, but I suspect it's probably
more like 10 minutes.

Most often I'm working with scanned engravings that have lots of
almost-parallel almost-horizontal lines, and the trouble is moiré-like
patterns that creep in. A gaussian blur before down-scaling, followed
by a sharpen, usually helps. We lost the old gimp 2.6 sharpen filter,
but the newer unsharp filter works.

Sometimes lohalo scales down without introducing the problems.
