I wonder if this is a duplicate of bug 2107741 which seems to have been
just fixed in Questing?

Title:
  Duplicate driver entries in software-properties-gtk on tab change

Status in software-properties package in Ubuntu:
  New

Bug description:
  When switching to the "Additional Drivers" tab in `software-
  properties-gtk`, the list of available drivers is duplicated every
  time the tab is changed. This results in multiple copies of the same
  driver options appearing in the interface.

  ---

  **Steps to Reproduce:**

  1. Open terminal and run:

     ```
     software-properties-gtk --open-tab=4
     ```
  2. Switch to a different tab (e.g., "Ubuntu Software") and then return to "Additional Drivers".
  3. Observe that the list of drivers is duplicated.
  4. Repeat the process — the list duplicates again with every tab switch.

  ---

  **Expected Behavior:**
  The driver list should remain clean and update only once. Switching tabs should not re-render additional copies of the existing list.

  **Actual Behavior:**
  Each time the "Additional Drivers" tab is opened, it adds another full set of the same drivers already shown. Even the "currently in use" driver is duplicated in each copy.

  ---

  **System Information:**

  * **OS:** Ubuntu 25.04
  * **Package:** `software-properties-gtk`
  * **Display server:** Wayland
  * **Graphics driver in use:** NVidia 570
  * **Observed consistently:** Yes, always reproducible.

  ---

  **Additional Notes:**

  * Behavior affects usability and may confuse users when selecting or changing drivers.
  * A video demonstration is available if needed.
