Public bug reported: After upgrading from Ubuntu 24.04 to 26.04, I can no longer create a new workspace by dragging a window in the Activities overview. When only one workspace has windows, dragging a window onto the empty workspace that peeks in at the right edge of the overview does nothing. When I release it, the window returns to its original position.
Steps to reproduce: 1. In Settings > Ubuntu Desktop > Dock, turn on "Auto-hide the Dock". 2. In the default Ubuntu session, keep all windows on a single workspace. 3. Open the Activities overview. 4. Drag a window onto the empty workspace visible at the right edge of the overview and release it. Expected result: The window moves to the empty workspace, and a new empty workspace is created after it. Actual result: The window snaps back to its original place on the current workspace. Nothing about the drop appears in the journal. What still works: - The keyboard shortcut Ctrl+Shift+Alt+Right moves the window to a new workspace. - Once two workspaces have windows, dragging windows between them works. Dropping a window on the empty workspace thumbnail at the end of the row at the top of the overview also works. Isolation: - With every Ubuntu extension disabled except the Ubuntu Dock, the problem still occurs. The Ubuntu Dock stays active in the Ubuntu session even after "gnome-extensions disable [email protected]". - In the plain GNOME session (gnome-session package), which runs without the Ubuntu Dock, dropping the window on the empty workspace at the screen edge works as expected. - Reinstalling gnome-shell-ubuntu-extensions did not change the behavior. dpkg --verify reports no modified files. - Turning off the dock's auto-hide (dock-fixed true) makes the drop work in the Ubuntu session. With auto-hide on (dock-fixed false), the window snaps back. The problem occurs only when the Ubuntu Dock runs with auto-hide on.
