Bug Report: Continuous text pasting/ghosting when panning on Ubuntu 26.04 (Firefox 150)

• OS: Ubuntu 26.04 LTS

• Browser: Firefox (version 150)

• Devices tested: Dell Inspiron 15 3530 and Dell Inspiron 3501

Problem Description

When using Figma in Firefox, an unexpected behavior occurs while panning (moving the canvas) with the cursor. The last sentence typed or copied starts appearing repeatedly across the screen, as if a "Ctrl + V" command were being triggered continuously.

This behavior only happens during canvas movement. As soon as the movement stops, the "pasting" effect ceases.

This bug directly impacts workflow, making Figma unusable in Firefox and forcing a switch to other browsers.

Steps to Reproduce

1. Open Figma in Firefox.

2. Access any file.

3. Type or copy any text string.

4. Move the canvas using the cursor (pan).

5. Observe that the text is repeatedly "pasted" or rendered across the screen during the movement.
