Description

When using `./install/delphyne-gui/bin/visualizer` (with configuration `./install/delphyne-gui/share/delphyne/layouts/layout_maliput_viewer.conf`) to view `./install/malidrive/share/malidrive/resources/odr/Figure8.xodr`, the visualizer consumes 100% of my CPU:

This makes my machine unresponsive and nearly unsable.

Victory condition: The visualizer does not take 100% of the CPU.

Research direction

Reproduce the issue with ./install/delphyne-gui/bin/visualizer, layout_maliput_viewer.conf, and Figure8.xodr as described. Trace the visualizer's CPU usage while this configuration is active; done means the visualizer no longer consumes 100% of the CPU or makes the machine unresponsive.
