Sorry you are running into this issue and thank you for filling this.

Look like there's a problem activating the conda env. Please can you try installing the previous version of python extension. Try 2024.2 and see if that makes a difference.

I'm having slowness in general when using vscode-remote. I had downgraded to 1.87.2 and it was much better. Sorry, it's so frustrating to work with Vscode sometimes...

[DonJayamanne]

We are currently working on some notebook performance related fixes in vscode. We have also identified some issues with the activation of conda envs and hopefully the fix will be shipped tomorrow (new version of jupyter and python extensions)

I'm sorry you are existing these issues and thank you for your patience.

Hello everyone :) For me, working in .ipynb files has recently become extremely slow. Could this also be related to this issue?

Typing text in cells, markdown or code, has a little bit of latency on startup already and it gets worse over time, it takes like 10 seconds at the moment.

any hints on how to fix this yet?

Thanks for your work and best regards! .martin

@martinscripts Can you try with a notebook without any markdown cells, and just a couple of code cells. Does that make a difference? Please can you share the notebook you are currently using?

[martinscripts]

unfortunately I can't share the notebook I am using because of sensible data. I tried to recreate it with just a part of it that I could share, but couldnt reproduce the problem.

But: If I delete all markdown cells, then it runs smoothly again.

I also use pasted images in my markdown cells. As well as some quarto yaml header in the very first cell, in case that matters.
