window list 'Close all/Close' somtimes cause desktop a halt and tab rearranged
When I use the close or close all to close some windows, The desktop is not responding, at least 10s, after the desktop will reopen(like the time that the desktop setup but no window is closed, so I think it's not a restart.) and the tab rearranged, especially when I open many windows(more than 15) or sometimes in high load. If the number of the windows is small, nothing bad happened and the window will close immediately.
