Environment data

• VS Code version: 1.47.0 insider
• Extension version (available under the Extensions sidebar): v2020.6.89148
• OS and version: XXX
• Python version (& distribution if applicable, e.g. Anaconda): 3.6
• Type of virtual environment used (N/A | venv | virtualenv | conda | ...): conda
• Relevant/affected Python packages and their versions: azureml
• Relevant/affected Python-related VS Code extensions and their versions: XXX

Expected behaviour

debug should have current line highlighted and automatically show variable values when hoverover

Actual behaviour

current only has an edit cursor on current line, not highlighted, no variable hove over value display. only happen on some packages(not all)

Steps to reproduce:

1. install package source code with pip install -e
   2.start a python file outside of package, and reference the code inside that package
   3.use vscode/python plugin to debug.
2. when step into code inside package, vscode does not highlight current line, instead it shows regular edit icon, debug can still work line by line, but without high light, I cannot hover over parameter and see values, has to manually add them to watch, pretty annoying.

Logs

Output for Python in the Output panel (View→Output, change the drop-down the upper-right of the Output panel to Python)

XXX

Output from Console under the Developer Tools panel (toggle Developer Tools on under Help; turn on source maps to make any tracebacks be useful by running Enable source map support for extension debugging)

I have the same problem too, however things seem to be weird: I have the same version of vscode and python plugin on my physical OS and virtual OS (both windows 10), however, the debugger of python in vscode performs greatly on my physical OS, yet no highlight on virtual OS. And if I change version of vscode to the last one, everything will be fine.

Installed packages are considered non-user code (same as standard library), and by default the debugger is configured to not debug it - so you can't step into it, breakpoints in it won't work etc.

If you want to debug installed packages, you need to set "justMyCode": false in your launch.json.

It is not the case.
I can step into package code, since I am using pip -e and package site in same folder as project I opened.
Debug can go line by line without issue and python executed in debugger perfectly.
It is just I cannot have current line high lighted.
It happened on some files but not others.

You can see that after starting the debugger, there's no highlight on the breakpoint line, only the cursor jumps to that line. I have tried to roll back vscode version to the last one, and the problem solved; however, after the auto update to lastest of vscode, the problem happens again.

Seems like my issue is stranger than this one: I didn't see this issue only appears on some packages, however mine appears on any code...

Since it's re-opened in vscode now, I'm going to close this one, so that there's only one open issue to track and comment on. If this turns out to be extension-specific after further investigation, please re-open.
