Hello everyone !
I tried to run the example camera_sensor.sdf. The simulation starts correctly, if I run it without subscribing to the /camera topic everything seems fine. But when I try to display the images taken by the camera in the 'Image Display' menu, everything freeze. Sometimes I can see one image before the simulation crashes. Is this because my PC is not powerful enough or does it come from somewhere else ? I'm on ubuntu 22.04, with 16 GB of RAM, a processor 11th Gen Intel® Core™ i7 and for the graphics I have a Mesa Intel® Xe Graphics (TGL GT2).
The terminal's output after the crash :
