In GNOME (but not in Weston), if a window loses focus, the client first receives the focus event, then the unlock/unconfine event. This causes toytoolkit to dereference a NULL window when unlocking or unconfining the pointer. To repro: - Run weston-confine - Click the window - Alt-Tab away from it Result: [1606837.869] wl_keyboard@19.modifiers(63944, 524352, 0, 0, 0) [1606837.926] wl_keyboard@19.leave(63945, wl_surface@15) [1606837.945] wl_pointer@18.leave(63946, wl_surface@15) [1606837.956] wl_pointer@18.frame() [1606837.961] zwp_confined_pointer_v1@26.unconfined() Segmentation fault (core dumped) To fix this, get the input from the window instead of the other way around.
