As of Qt 5.5.0, plugging in or unplugging an input device with a Qt application running prevents the awesome window manager from receiving mouse input events. Other applications continue to work as expected.
For non-root windows, this was fixed by setting the appropriate XCB event mask. However, the fix does not seem to be applicable for the root window.
Setting QT_XCB_NO_XI2_MOUSE=1 works around the problem.
