Invisible step marker in the source code #2835
Description
Describe the problem
Invisible step marker in the source code during step-by-step debugging
The instructions clearly identify the line in the source code. (Image excerpt from https://docs.arduino.cc/software/ide-v2/tutorials/ide-v2-debugger/)
This marker is not displayed in my IDE. Only the grey highlight of the line is moved (see photo).
Debugging works in principle, but is very difficult to track.
