Pippin, thanks! I completely forgot to ask the main question, which was whether to post a GIMP or a GEGL bug report.


Scaling up or down using nohalo produces a partially transparent border
around the layer if the layer has an alpha channel. This is a long-standing
issue that still obtains (at least scaling down has produced the edge
artifact for a long time, bug 698601 describes the opposite situtation for
scaling up).

I only just discovered that removing the alpha channel at least sometimes
allows to scale a layer without creating the edge artifacts. So I'm not sure
if removing the alpha channel always allows to scale without creating edge

This bug was confirmed using babl/GEGL/GIMP updated today.

Should I file a new bug report? or maybe instead open one of the old bug
