https://bugs.kde.org/show_bug.cgi?id=479321 --- Comment #3 from Freddie Witherden --- It is easy to reproduce on my 14 core (20 thread) system when the "Process" view is open. Monitor chews up an entire CPU core and is entirely unresponsive. Attaching `perf` and checking the results we find: 5.35% plasma-systemmo libQt6Core.so.6.7.2 [.] 0x002e0525 5.34% plasma-systemmo libQt6Core.so.6.7.2 [.] 0x002e0552 4.68% Thread (pooled) libc.so.6 [.] malloc 4.28% plasma-systemmo libQt6Core.so.6.7.2 [.] QObjectPrivate::maybeSignalConnected 4.09% plasma-systemmo libQt6Core.so.6.7.2 [.] 0x002e0520 4.01% plasma-systemmo libQt6Core.so.6.7.2 [.] 0x002e0465 1.40% plasma-systemmo libQt6Core.so.6.7.2 [.] 0x002e05e3 1.21% Thread (pooled) libc.so.6 [.] cfree 0.96% Thread (pooled) libQt6Core.so.6.7.2 [.] QCoreApplication::postEvent 0.92% Thread (pooled) libc.so.6 [.] __tfind 0.87% Thread (pooled) libglib-2.0.so.0.7800.6 [.] g_main_context_wakeup 0.74% Thread (pooled) libQt6Core.so.6.7.2 [.] QObject::~QObject Another item I found when digging through the call graph is QAbstractItemModel::dataChange. This suggests it is UI related. -- You are receiving this mail because: You are watching all bug changes.
