Can't drag GameObject from Hiearchy to Project view to create prefabs on Linux unity 5.5.1

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:

  1. Create an empty game object
  2. 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.

I’m using propretary NVidia drivers 375.26 and working on multiple displays.

Ok, got it, problem happens on linux when Unity windows are split in multiple screens and the other window is ful screen. Could be due to a gnome extension I use. Anyway, Closing or making the second window smaller allows me to create prefabs again.

I should fill a bug report for this.
