It would be really nice if the ‘Outliner-glitch’ could be fixed. It slows down work and visually distracts. It happens when:
- moving stuff - a group or even a single edge (2 times dance)
- entering or leaving a group in the viewport (1 time)
- adding a group (2 times)
- deleting loose edges or a group (1 time)
- changing the view to another scene (1 time)
Edit2: it seems like its an old bug. The duration of the glitch depends on the size of the object hierarchy.
