This totally looks like a bug with Unity3d and Gnome. I’m not a pro with Unity3d yet, but I defnitely know how to create a prefab. Also note that dragging a prefab from scene to Project files also fails.
I’m able to do this on Windows, on MacOS, but it doesn’t work on Fedora. A friend runs on Ubuntu and it seems to work.
Currently happens on 5.5.1xf1Linux and probably other versions, drag n drop is always glitchy in Unity Editor.
Steps to reproduce:
- Create an empty game object
- Drag the object from Hiearchy view to Project view
Fails when dragging on Folders and blank spaces. I don’t have any popup in front or behind unity.
