How to reproduce:
- Open Unity Hub
- Close the Unity Hub window by pressing the "X" button at the top right of the window
- Reopen Unity Hub by pressing the Super key, typing "Hub", and selecting "Unity Hub"
- Open the GNOME Activities Overview by pressing the Super key
- Observe the Unity Hub window in the Activities Overview
Actual result: The Unity Hub window is not scaled down into a window preview - it stays at its full desktop size, shifts towards the bottom-center of the screen, and cannot be clicked or hover-focused
Expected result: The Unity Hub window is scaled down into a window preview like the other open windows and can be selected with the mouse
Reproducible with: 3.21.0
Reproducible on: Ubuntu 24.04 LTS (Wayland session)
Not reproducible on: Ubuntu 24.04 LTS (X11 session)
Workaround:
Right after reopening the Hub window, do one of the following:
- Resize the window by dragging its border
- Maximize the window by pressing the maximize button or by double-clicking the title bar
- Minimize the window
Alternatively, the issue does not occur when the Hub window was maximized when it was closed, or when it was minimized and closed without being restored (by pressing the "X" button on its preview in the Activities Overview).
Notes:
- The window is scaled down correctly in the Activities Overview on the first launch after the Hub process has been fully quit; the issue only appears after the Hub window has been closed and reopened
- Once the Activities Overview has been opened while the issue is present, the Hub window can no longer be resized by dragging its borders
- Also reproducible with the Hub version prior to 3.21.0 (before the Electron icon fix)
