With FURY master strange window appears when new actors are created

[nasimanousheh]

Description

In latest master a vtk popup window appears when actors are created. No issues with previous versions. For example all good with the freehand-drawing PR which is a recent PR.

Hard to debug as there are no error messages. Maybe those are encapsulated in the vtk popup window but are not visible to the human eye.

Any ideas? I noticed this issue while working with Furious Atoms. (https://furiousatoms.com)
