SUMMARY When screen reader is on, hovering a task bar entry or doing pretty much everything causes Plasma to crash. STEPS TO REPRODUCE 1. Start Orca from accessibility KCM 2. Restart plasmashell 3. Use plasmashell OBSERVED RESULT It crashes all the time EXPECTED RESULT It doesn't crash SOFTWARE/OS VERSIONS Linux/KDE Plasma: (available in About System) KDE Plasma Version: 5.19.0 git master KDE Frameworks Version: 5.71.0 git master Qt Version: 5.14.2 ADDITIONAL INFORMATION [KCrash Handler] #4 0x0000000000000000 in () #5 0x00007feef7379317 in QQuickItemLayer::~QQuickItemLayer() (this=0x559244cb1560, __in_chrg=<optimized out>) at items/qquickitem.cpp:8298 #6 0x00007feef7379389 in QQuickItemLayer::~QQuickItemLayer() (this=0x559244cb1560, __in_chrg=<optimized out>) at items/qquickitem.cpp:8300 #7 0x00007feef7525d72 in QAccessibleQuickItem::role() const (this=0x5592438db1b0) at accessible/qaccessiblequickitem.cpp:211 #8 0x00007feee6664301 in AtSpiAdaptor::pathForInterface(QAccessibleInterface*) const (this=this@entry=0x559240467f80, interface=0x5592438db1b0) at atspiadaptor.cpp:1538 #9 0x00007feee6666d14 in AtSpiAdaptor::notifyStateChange(QAccessibleInterface*, QString const&, int) (this=this@entry=0x559240467f80, interface=<optimized out>, state=..., value=1) at atspiadaptor.cpp:873 #10 0x00007feee6668054 in AtSpiAdaptor::notify(QAccessibleEvent*) (this=0x559240467f80, event=<optimized out>) at atspiadaptor.cpp:898 #11 0x00007feef7385f48 in QQuickItemPrivate::setEffectiveVisibleRecur(bool) (this=this@entry=0x559242bd0160, newEffectiveVisible=<optimized out>) at items/qquickitem.cpp:6079 #12 0x00007feef738c492 in QQuickItem::setParentItem(QQuickItem*) (this=this@entry=0x559244cb1560, parentItem=parentItem@entry=0x0) at items/qquickitem.cpp:2789 #13 0x00007feef738e108 in QQuickItem::~QQuickItem() (this=0x559244cb1560, __in_chrg=<optimized out>) at items/qquickitem.cpp:2390 #14 0x00007fee19306d7d in () at /usr/lib/x86_64-linux-gnu/qt5/qml/QtQuick/Templates.2/libqtquicktemplates2plugin.so #15 0x00007feef34635a5 in QObject::event(QEvent*) (this=this@entry=0x559244cb1560, e=e@entry=0x559243ff9a80) at kernel/qobject.cpp:1326 #16 0x00007feef738b4db in QQuickItem::event(QEvent*) (this=0x559244cb1560, ev=0x559243ff9a80) at items/qquickitem.cpp:8162 #17 0x00007feef47749ac in QApplicationPrivate::notify_helper(QObject*, QEvent*) (this=this@entry=0x55923d76f7a0, receiver=receiver@entry=0x559244cb1560, e=e@entry=0x559243ff9a80) at kernel/qapplication.cpp:3685 #18 0x00007feef477bbb0 in QApplication::notify(QObject*, QEvent*) (this=0x7ffdd2673d60, receiver=0x559244cb1560, e=0x559243ff9a80) at kernel/qapplication.cpp:3431 #19 0x00007feef34304a8 in QCoreApplication::notifyInternal2(QObject*, QEvent*) (receiver=0x559244cb1560, event=0x559243ff9a80) at kernel/qcoreapplication.cpp:1075 #20 0x00007feef343067e in QCoreApplication::sendEvent(QObject*, QEvent*) (receiver=receiver@entry=0x559244cb1560, event=event@entry=0x559243ff9a80) at kernel/qcoreapplication.cpp:1470 #21 0x00007feef3433121 in QCoreApplicationPrivate::sendPostedEvents(QObject*, int, QThreadData*) (receiver=receiver@entry=0x0, event_type=event_type@entry=0, data=0x55923d763fe0) at kernel/qcoreapplication.cpp:1815 #22 0x00007feef34336b8 in QCoreApplication::sendPostedEvents(QObject*, int) (receiver=receiver@entry=0x0, event_type=event_type@entry=0) at kernel/qcoreapplication.cpp:1674
Appears to be the media controller applet. :/ It also just crashes when run through plasmawindowed
Looks like PlasmaComponents3 ComboBox. When I swap it out for a QQC2 one it works. However, I tried porting ComboBox to ShadowedRectangle and it didn't fix the issue, despite backtrace suggesting something in layers.
The Media Controller applet no longer uses a combobox, so I imagine this is fixed. Can you still reproduce it in other contexts with PC3 comboboxes?
