AFAIK embedded GOP objects have always had frames. This is why all 
iemguis also have frames/inlets/outlets even when embedded inside GOP. I 
think your background made them hard to distinguish. I could be wrong, 
though, but I always remember seeing those.

As for the text not being displayed, can you send me the slider 
abstraction? It could be that since you've originally saved the 
abstraction inside regular pd that it did not get adjusted completely to 
conform to pd-l2ork's way of dealing with these. Try manually 
readjusting the GOP size and re-save it. It should either prevent you 
from resizing it below the text size or do it just fine provided you've 
disabled the showing of text. As for text not showing in a subpatcher 
even though it should, this is something I should investigate.

This likely refers to text encoding if you use something
