Icons are not correctly loaded if the dependencies are installed from apt

If I installed the visualizer from pip the incons are correctly loaded

pip list

On the other hand If I installed from the superbuild I got the following error

qt.svg: Invalid path data; path truncated.
qt.svg: Invalid path data; path truncated.

and some of the icons are not shown correctly. In this context pyqt5 is installed from apt. I'm experecing the issue on ubuntu 22.04. Notice that in ubuntu 22.04, the version of pyqt5 is 5.15.6 (the same of pip) (https://repology.org/project/python:pyqt5/versions)

Related issue: #40 .
Can you report the output of pip list --verbose ? It can be helpful to understand which dependencies where installed by apt and which one via pip.
