Viztracer/vizviewer displays only 1 of N threads with the same name

[olumide-x]

I'm tracing a MT application that creates several threads with the same name to run the same function albeit with different inputsbut when I run vizviewer I only see one instance of those threads. Does viztracer/vizviewer cache threads by name?

No it does not use the thread name, it uses the thread ID. Could you share a minimum reproducible example?
