Application: plasmashell (6.0.1) Qt Version: 6.6.2 Frameworks Version: 6.0.0 Operating System: Linux 6.6.20-1-lts x86_64 Windowing System: Wayland Distribution: Arch Linux DrKonqi: 6.0.1 [CoredumpBackend] -- Information about the crash: This crash occured right when I used a KVM switch to connect my second display (a Dell UP3218K 8K display, which is an older multi-tile design that has 2 4K panels side-by-side) and a USB mouse and keyboard. The crash occurred immediately after activating the KVM switch. The KDE Plasma system did not succeed in displaying an image on the monitor -- it remained black. The reporter is unsure if this crash is reproducible. -- Backtrace (Reduced): #5 std::__atomic_base<int>::fetch_add (__m=std::memory_order_acq_rel, __i=1, this=0x7babe6333930 <QV4::Value::toBooleanImpl(QV4::Value)>, this=<optimized out>, __i=<optimized out>, __m=<optimized out>) at /usr/include/c++/13.2.1/bits/atomic_base.h:633 #6 QAtomicOps<int>::ref<int> (_q_value=std::atomic<int> = { -98693133 }, _q_value=<optimized out>) at /usr/src/debug/qt6-base/qtbase-everywhere-src-6.6.2/src/corelib/thread/qatomic_cxx11.h:258 [...] #8 QtSharedPointer::ExternalRefCountData::getAndRef (obj=obj@entry=0x64ab2cbea120) at /usr/src/debug/qt6-base/qtbase-everywhere-src-6.6.2/src/corelib/tools/qsharedpointer.cpp:1409 #9 0x00007babe5692170 in QWeakPointer<QObject>::QWeakPointer<QObject, true> (ptr=0x64ab2cbea120, this=<optimized out>) at /usr/src/debug/qt6-base/qtbase-everywhere-src-6.6.2/src/corelib/tools/qsharedpointer_impl.h:685 #10 QWeakPointer<QObject>::assign<QObject> (this=0x64ab323e5870, ptr=0x64ab2cbea120) at /usr/src/debug/qt6-base/qtbase-everywhere-src-6.6.2/src/corelib/tools/qsharedpointer_impl.h:680 Reported using DrKonqi

Looks like it would be a Qt bug to me.
I agree, looks like Qt bug
