I've been trying to solve this crash and I might have found the way.

EDITED: See #466 (comment)

Old comment:

Syncing with the `QuickWindow` that emits a signal called `Qt::BeforeRendering` seems to be the way to go.
For example, [the `Grid3D` built-in plugin](https://github.com/ignitionrobotics/ign-gui/blob/242dd40ca0181e5a156225b5d4b1599ed9694b6d/src/plugins/grid_3d/Grid3D.cc#L199-L200) uses that technique also.

I've tried it locally, grouping the mesh rendering all synced with the `BeforeRendering` signal, and that solved the issue.
https://github.com/ToyotaResearchInstitute/delphyne_gui/commit/cf721fe4feef6374533431c0964eb0832e3b4e1b

We have to fix this for:
 - MaliputViewerPlugin: In this particular plugin, entities in the scene are modified from different methods.
    - For Road Meshes.
    - For Label mesehs.
    - For Lane selector.
    - For the Arrow.
    - For the TrafficLightManager.
 - OriginDisplay
 - AgentInfoDisplay

This #466 (comment) isn't accurate.
The way we are hooking to the Render event is ok and that's the recommended way.

This crashes seems to be related to the way we initialize the plugin. Plugins that needs to be fixed:
