Sometimes Interactive Window doesn't display the input code.

[forestGoroli]

Applies To

• Notebooks (.ipynb files)
• Interactive Window and/or Cell Scripts (.py files with #%% markers)

What happened?

Simplified reproduction method for my own use.

1. Prepare many cells (more than 5?) and Run from "Jupyter: Run All Cells."
2. Run the code from the interactive cell a few times (around 5).
3. Sometimes window doesn't display the input code. (Output is still showing.)

The attached image is an example of this bug.

1. I prepared the code consisting of 9 cells (1 for markdown, 8 for dummy code).
2. Then I typed "print('aa')" into the interactive window 5 times.
3. 3 / 5 of the input cells don't display my code.
   
   

I've also used the interactive window for debugging the short code, so not displaying my input code is a little unusable.

I have the same issue. I think the earlier VSCode release did not have this problem.

Thank you very much!
I faced this problem after February, so as you said, I think this problem is only for the latest version (v2023.1.2000312134).

Experiencing the same issue as well.

I tried installing version v2022.11.1003412109 with the latest VSCode release.

1.75.0

It gives the same problem. Could this be a VSCode issue?
There seems to be an issue about this already: #173300

This issue is important... I need to be collapsing and expanding cells all the time, to be able to see the code.

I see this problem too but it appears to only fail to render the code cells when I have both the code and output expanded. If I collapse the output then I can scroll away from a code cell (out of view) then back to view without an issue. If both the code and output are expanded, scrolling away and back results in the code cell not rendering until it is collapsed and expanded again.

Can anyone help open Developer Tools (F1 -> Toggle Developer Tools) and share errors/logs in the dev tools with us to help troubleshoot?

[PlanoCode]

@rebornix Looking at the console of the dev tools, all scrolling produces lots of the attached errors. It happens scrolling in either direction, it happens if only collapsed code/output sections are visible, it happens with expanded code/output sections. If you scroll so that an expanded code and output cell are out of view, then scroll back the code cell does not appear. The height of the cell is unchanged but all of it's contents are missing including the lighter grey box where the text/code would usually appear.

EDIT:
Some more curious details, if I expand all cells I continue to get the same error but only when the top of a new code cell comes into view. So when you scroll down the page as soon as a new cell comes into view you receive the error but scrolling up you can see the bottom of the cell without a new error occurring until you reach the top of the cell and it is completely in view.

Also with all cells expanded I do not have the issue with any of the cells disappearing and I do not need to collapse and expand a code or output cell to make the code cell's contents visible.

@PlanoCode thanks for providing the logs and reproduce steps! Your reproduce steps made me wonder if anything goes wrong with the collapse cell initial rendering, it would be great if you can share all logs you saw in Developer Tools as it seems that the log you shared is not the one leading to the bug.

@rebornix I am continuing to use the notebook and that that appears to be the only error I receive:

Collapsing a code cell does not appear to trigger any new messages except if doing so causes an code cell to come into view (does not cause an error if a MD or Output cell comes into view.) In my test even if I collapse all the code cells and expand one toward the top, once I collapse it I will receive that message on the console for every collapsed code cell that comes into view (ex 8 messages if there are 8 code cells, 1 output and 1 markdown (all collapsed))

[rebornix]

@PlanoCode I can now reproduce the issue with the steps you provided, will fix it in Insiders tomorrow and have it fixed in VS Code recovery build. Thank you for the patience and help with the troubleshooting.

[rebornix]

The fix will be available in tomorrow's Insiders and also the next Stable recovery build (in a couple of days).
