Description vanyossi 2014-02-26 22:20:12 UTC

After deleting all layers inside a group contents remains in display as if the group had layers. The group ghost contents disappear after adding one empty layer but reappear if group is left empty again.

Reproducible: Always

Steps to Reproduce:
1. Create a group layer with 2 paint layers in it (It only works with more than one layer inside the group)
2. Paint something in both layers
3. Delete layers leaving the group empty
Actual Results:  
Deleted pixel data reappears in the group

Expected Results:  
group layer should display nothing if empty.

Thanks, I can confirm. Dmitry, do you have an idea what's going on here?

Comment 2 Dmitry Kazakov 2014-02-28 09:36:44 UTC

Yes, the content of the  group's projection is not updated after all the child layers got removed, so it is updated only when you add any child layer. That is a bug, yes.
