Hey guys,
I started learning Monogame recently and I have been running into a couple of really weird bugs when using the Content Pipeline. When I try to add content/folders clicking with the right button of the mouse, I get the following error:
System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.NullReferenceException: Object reference not set to an instance of an object at Gtk.Menu.PopupAtPointer (Gdk.Event trigger_event) [0x00014] in <f775ff7b2e4a42d992aca2c382879b7c>:0 at Gtk.Menu.Popup () [0x00000] in <f775ff7b2e4a42d992aca2c382879b7c>:0 at Eto.GtkSharp.Forms.Controls.GridHandler2+GridConnector[TWidget,TCallback].HandleButtonPress (System.Object o, Gtk.ButtonPressEventArgs args) [0x000f7] in <3bbc1daff97142648cd48237c49932b3>:0

I tried fixing it reinstalling Mono, Monogame, gtk-sharp3 but none of them worked. I think is probably something wrong with my Linux (Ubuntu 16.04) but I haven’t been able to pinpoint the issue. I am using mono 5.18.0.240
Did someone experience something similar?
Additionally, I get two different windows when I run the Content Pipeline depending if I use sudo to start it.
Without sudo
With sudo
