REVISION SUMMARY CCBUG: 358231 CCBUG: 342056 Even the icon with the number of tasks pending moves from time to time. To reduce the lock up time, a similar patch must be applied also to frameworks/kwindowsystem src/platforms/xcb/kxmessages.cpp frameworks/plasma-framework src/plasma/private/effectwatcher.cpp According to the documentation (and a look to the source code) http://doc.qt.io/qt-5/qabstractnativeeventfilter.html The type of event eventType is specific to the platform plugin chosen at run-time, and can be used to cast message to the right type. On X11, eventType is set to "xcb_generic_event_t", and the message can be casted to a xcb_generic_event_t pointer. The other eventType are "windows_generic_MSG" and "mac_generic_NSEvent". No other eventType starts with an 'x'. TEST PLAN Cut & paste 2000 small files.
