Cursor IDE
Describe the Bug
When using the Agent within the Cursor editor, the text cursor consistently and unexpectedly jumps to the beginning of the current input/line. This happens during normal typing and when using the Backspace key, resulting in text being inserted backwards.
Important Discovery: This bug is strictly isolated to when the Agent is popped out into an independent/floating window. If the Agent is docked in the main window, typing functions normally.
Steps to Reproduce
-
Open Cursor.
-
[CRITICAL STEP] Pop the Agent out into a separate, independent window. (see attached screenshot showing the “Agents Window”)
-
Focus the input field in this separate window and attempt to type the word cat.
-
Type c. The cursor immediately jumps to the far left: |c.
-
Type a. Because the cursor is at the beginning, it inserts before ‘c’, resulting in |ac.
-
Type t. The final text becomes tac instead of cat.
-
Alternatively, place the cursor at the end of a word and press Backspace. The cursor immediately relocates to the far left instead of deleting the previous character.
Expected Behavior
The text cursor should maintain its correct position relative to the user’s input, even when the Agent is operating in a separated window.
