When running the examples in 5.3 - Callbacks, I am unable to see the graphical tool. When running the “ros2 run” command, sometimes the windows does not even open, other times it opens but only shows a background image.
Here is the terminal information:
user:~/ros2_ws$ ros2 run ros2_callback_visualiser analise_trace_calback_function.py
converting trace directory: /home/user/.ros/tracing/callback_function
converted 138 events in 24 ms
output written to: /home/user/.ros/tracing/callback_function/converted
