Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

The “undo” button almost always disappears, and it only reappears occasionally when scrolling or moving the mouse. Could this be a specific layout bug in Chinese?

Steps to Reproduce

Stably reproduce in the chat window

Expected Behavior

It is necessary to have a stable display of the undo button. If this function can be provided stably, it would be preferable to place it in a fixed toolbar rather than hiding it in various locations.

Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey there! That’s the Restore Checkpoint control (docs) - it’s dropping off the timeline until the row re-renders. To get it back now, hover over or scroll past that request and it reappears (still clickable).

This isn’t something on your end. A fix is already in the works and should land in an upcoming update, so staying on the latest version is the way to pick it up. Follow along here: Revert / Restore Checkpoint button missing.
