Please create a new report about the EGID suggestion.

Hmm, so there's effective GID and the process GID.

The GID it shows should indeed be the EGID it seems.  Is this what other apps do?

It's what ps does. But there are so many ?GID-s that it may be a good idea to avoid having a "GID".

Get the effective etc GIDs and UIDs for the process.
