REVISION SUMMARY Several effects announce a support property atom on the root window. This change forwards the KWin::Application's signal that the xcbConnection changed to the EffectsHandler so that the effects can respond to it. All effects which announce a support property connect to this new signal and re-announce the property. In case the xcb connection died (future XWayland crashing case) it is set to XCB_ATOM_NONE by that. In case the xcb connection got created (future delayed XWayland startup) the atom is set to the proper value. In addition all usages of the support properties are guarded, so that no nonesense actions are performed if the support property is XCB_ATOM_NONE. TEST PLAN Only compile tested as we don't have XFree KWin yet REPOSITORY R108 KWin BRANCH effects-xcb-connection-changed REVISION DETAIL https://phabricator.kde.org/D7761 AFFECTED FILES effects.cpp effects/backgroundcontrast/contrast.cpp effects/blur/blur.cpp effects/highlightwindow/highlightwindow.cpp effects/kscreen/kscreen.cpp effects/presentwindows/presentwindows.cpp effects/slidingpopups/slidingpopups.cpp libkwineffects/kwineffects.h To: graesslin, #kwin, #plasma Cc: plasma-devel, kwin, bwowk, ZrenBot, progwolff, lesliezhai, ali-mohamed, hardening, jensreuterberg, abetts, sebas, apol, mart
