Scrolling causes screen flicker

[itsmoa]

Description

when attempting to scroll up and down the jupyter notebook page on chrome, at a certain point it flickers, and it wont go up and down, there is no control of the flickering, until it stops by itself

To reproduce

1. just scroll down through the page
2. notice how the scroll bar keeps jumping back up

Trouble shooting steps

• Hard Refresh the Browser (Ctrl + Shift + R / Cmd + Shift + R)
• Tried a Different Browser (Chrome, Firefox, Edge, Incognito Mode)
• Cleared Browser Cache & Cookies
• Disabled Browser Extensions (especially UI-related ones)
• Cleared Jupyter UI State via Console (localStorage.clear(); location.reload();)
• Checked Browser Console (F12 → Console) for Scroll Errors
• Tried Running window.onscroll = null; in Console to Stop Auto-Scrolling
• Jupyter & Anaconda Configurations
• Disabled Jupyter Auto-Scrolling with a Custom CSS Override

Edited ~/.jupyter/custom/custom.css:
body { overflow: auto !important; }

• Reset Jupyter UI by Clearing LocalStorage

• Generated a New Jupyter Configuration File (jupyter notebook --generate-config)

• Deleted the Existing Jupyter Config File

• Tried Running Jupyter in Safe Mode (jupyter notebook --NotebookApp.disable_check_xsrf=True)

• Tried a Different Terminal (Command Prompt, PowerShell) Instead of Anaconda Navigator

• Disabled Jupyter Themes (pip uninstall jupyterthemes -y)

• Jupyter Updates & Reinstallation

• Updated Jupyter Notebook (conda update jupyter notebook)

• Tried an Older Jupyter Version (pip install notebook==6.5.4)

• Uninstalled and Reinstalled Jupyter (pip uninstall jupyter notebook -y && pip install jupyter notebook)

• Fully Removed and Reinstalled Anaconda

• Launched Jupyter in a Fresh Python Virtual Environment (conda create -n test_env python=3.9)

• System-Level Fixes

• Checked for External Mouse/Keyboard Issues (Tested with Trackpad)

• Tested Jupyter Notebook on a Different User Account

• Checked If Other Jupyter Interfaces Work (jupyter lab)

• Tried Running Jupyter with No Browser (jupyter notebook --no-browser)

• Ran Jupyter Inside Windows Subsystem for Linux (WSL) (Official Build) (64-bit)

• windows 11 home OS. 26100.3037

• google chrome Version 132.0.6834.160 (Official Build) (64-bit)

• Jupyter Notebook version: Version: 7.3.2

Thanks @itsmoa for the report.

Do you know if this also happens when using JupyterLab?

Hey Jeremy, Yes it happens in Jupyterlab too. Best Regards, Michael Akeredolu

Thanks @itsmoa.

Since both Jupyter Notebook and JupyterLab use the same notebook component, would you be able to open the issue on the JupyterLab repo? https://github.com/jupyterlab/jupyterlab

Thanks!

Just posted it @jtpio - here is the link to that one jupyterlab/jupyterlab#15795 (comment)

Seems like these steps solved my issue - gotten from @krassowski jupyterlab/jupyterlab#15795 (comment)

In Settings Editor → Notebook → Windowing mode - Defer

I could solve the flickering issues by making the following changes to the Jupyter notebook 7.3.2 version:

Settings Editor → Notebook → Windowing mode - Defer

Thanks!

I had the same issue but in text editor of JupyterLab -- the same fix outlined here also works within the text editor.
