** Description changed: [ Impact ] When a maximized window is dragged down from gnome-shell's top panel to un-maximize it with touchscreen, it will freeze the whole window manager: existing content will continue to animate, but input is unresponsive. + + This bug only affects GNOME on X.org, so Ubuntu 25.10 and newer are + unaffected. [ Test plan ] 1. Log into Ubuntu (on Xorg) 2. Open any window 3. Maximize it 4. With a touchscreen, drag downwards from the top panel of gnome-shell 5. Verify that the window was unmaximized 6. Verify that the window follows the finger [ Regression test plan (x11) ] 1. Log into Ubuntu (on Xorg) 2. Open any window 3. Maximize it 4. With a touchscreen, drag downwards from the top panel of gnome-shell 5. Verify that the window follows the finger 6. Add a second finger on the window 7. Verify that the second finger is ignored, and the drag continues normally [ Regression test plan (wayland) ] 1. Log into Ubuntu (on Wayland) 2. Open any window 4. With a touchscreen, drag the window aroud 5. Verify that the window follows the finger 6. Add a second finger on the window 7. Verify that the second finger is ignored, and the drag continues normally 8. Verify that GNOME Shell did not crash and log you out [ Where problems could occur ] The patch changes which inputs are accepted during a compositor-side window drag. If too many, you may see other input interfering with the drag operation. If a bug is introduced, in the worst case the compositor may crash and log you out while dragging a window on Wayland.
