Cursor position issue in Azure Databricks

Question

Hi, when editing code inside Databricks notebook environment, the cursor does not position itself at where I thought I was typing. There seems to be difference in 5-6 character positions between where the cursor is and where characters are entered/deleted.

This problem exists whether using Edge or Chrome browser, but I don’t seem to have problem when on Safari browser.

Tried methods suggested like changing browser (didn’t work for Chrome or Edge), clearing cache, turning off autocompletion, but they didn’t work.

Hi @Hong Ling TAN (NP) What you're experiencing sounds like a rendering issue with the Monaco editor in Databricks notebooks, particularly tied to how the browser handles fonts, scaling, or GPU acceleration.

A few advanced troubleshooting steps that often resolve cursor misalignment issues:

1. Browser Zoom and Display Scaling: Ensure your browser zoom is exactly 100% and check your OS-level display settings. On Windows, high DPI scaling (e.g., 125% or 150%) can cause cursor offset issues in web-based editors.
2. Disable Hardware Acceleration: In Chrome or Edge, go to: Settings > System > Use hardware acceleration when available → Turn this off, then restart the browser.
3. Test with Extensions Disabled: Try opening the notebook in Incognito/Private mode. Some extensions (e.g., password managers, grammar checkers) can interfere with the notebook UI.
4. Fonts or Custom Themes: Avoid custom font rendering tools or browser themes. These can subtly shift text positioning and affect cursor alignment.

Since it works fine in Safari, it’s likely something browser-specific rather than an actual issue with Databricks itself.
