Start by reproducing the issue in Update Manager on Linux Mint Cinnamon 22.x: minimize the window during an update, switch workspaces, and continue working. Trace the install progress and post-install update-check behavior, including the Flatpak progress bar. Done means a minimized manager stays minimized and progress surfaces do not capture or appear in another workspace unless the manager has focus.
