Re: [Gimp-developer] Border artifact from using nohalo to scale a layer with an alpha channel

In general it is better to open new bug-reports, rather than re-open
old ones seeming similar - long threads of possibly different problems
discussed in comments makes it hard to follow progress of an issue.
This issue seems like it might already have a bug though bug #698468.

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
