Built-in browser tab covers up application tooltips

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

The browser in the browser tab appears to have a very high z-index, which is above that of the various tooltips or popups from the IDE itself. This causes the browser to cover up popups that should be clearly visible on top of the browser window, such as the cursor update notification.

Steps to Reproduce

  1. Open a webpage in the built-in browser tab
  2. To make it easy, hide the bottom terminal panel so the browser tab goes to the bottom of the IDE
  3. Wait for Cursor to make an update notification

Expected Behavior

The popup/tooltip from the IDE should sit over the browser tab content and be fully visible

Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey, thanks for the report. I can see a screenshot where the update notification is being covered by the browser.

This is a known issue with the built-in browser layer z-index. The team is working on a fix for these kinds of UI overlap problems.

As a temporary workaround, you can close the browser tab when you need to interact with IDE pop-up notifications.

Your report will help us prioritize fixing this issue.
