Unable to Scroll Up in Jupyter Notebook #7520
Comments
This persists across different machines. Tried it on my Windows 10 and MacOS as well. Every time I scroll up, it pulls up down to the starting position randomly. |
Thank you for opening this issue @ruidazeng! Could you share the version of Jupyter Notebook that you are using? We were not able to reproduce this on the triage call, but if you could share a video of the steps to reproduce and the behaviour you are seeing that may be helpful! |
This is quite likely jupyterlab/jupyterlab#15795 The exciting part is that you say you can reproduce this reliably. If you can share the notebook which allows that and exact repro instructions as mentioned by Rosio I may be able to fix it. |
I am using Jupyter 7.2.2 notebook. It seems similar to jupyterlab/jupyterlab#15795 indeed, I am unable to scroll away from active cells randomly. Sometimes I can, sometimes I can't, but this issue persists across my two laptops. |
@ruidazeng thank you for the follow-up information! If you find a case where this can be reproduced consistently and can by any chance share the notebook file contents, that would be helpful! Also, although you are using Notebook and if you can try out JupyterLab 4.4.0a0 which includes Mike's fix (jupyterlab/jupyterlab#16950) and provide any feedback in the JupyterLab issue, that would be great! |
I am not able to share the exact notebook file contents, but essentially what I've noticed is this behavior tend to happen when I am doing the following three things: (1) when I am using Python (2) when I am using Python (3) when i am using Python's default |
Any chance you could provide a sanitized version of the affected notebook? I tried reproducing going by (3) and could not reproduce it:
(the recording is choppy but scrolling locally is smooth) |
I'm able to reproduce reliably with the attached R notebook Preface.ipynb.txt. I added the extension ScrollResetFromBottom.webm |
Does this happen on other notebooks for you as well? @krassowski I have tried to sanitize it but after sanitation the bug isn't being re-produced reliably like before anymore |
This should normally be fixed in the notebook 7.4 pre-release: https://github.com/jupyter/notebook/releases/tag/v7.4.0a0 If you want to try to make sure that's the case:
For now the fix is only available in these JupyterLab 4.4 and Notebook 7.4 pre-releases. But it could be backported to 4.3.x / 7.3.x if it doesn't have undesired side effects. |
Description
When attempting to scroll up in a Jupyter notebook, the view automatically bounces back down to the current position. This prevents the user from reviewing earlier cells or content above the current view.
Reproduce
Expected behavior
It should let me scroll up.
