Created attachment 187392 [details] Photo of screen *after* system-freeze/kernel panic. RAM allocation history and plasmashell RAM use are visible. SUMMARY Plasmashell freezes with a violent memory runaway when closing the system-tray notification widget before the system tray has been opened STEPS TO REPRODUCE 1. Log into Plasma *without* notification widget pinned in system tray on panel 2. Right click tray arrow (do not open!) 3. Click "Configure System Tray", go to "Entries"-tab 4. Set "Notifications" element to "Always shown" 5. Click Notification Icon in System Tray on Panel 6. Click Back-Button on top left of Mini Program OBSERVED RESULT - Panel, Tray and Widgets freeze - CPU-Usage skyrockets on one core - Memory use surges, allocating at around 0.5G/sec - When Memory (&Swap) is full, system freezes (probably Kernel Panic, but I don't know how to confirm that) EXPECTED RESULT Either: Notification Widget closes Or: Back into general System Tray SOFTWARE/OS VERSIONS Operating System: Arch Linux (fully updated) KDE Plasma Version: 6.5.3 KDE Frameworks Version: 6.20.0 Qt Version: 6.10.1 Kernel Version: 6.17.9-zen1-1-zen (64-bit) Graphics Platform: Wayland Processors: 16 × AMD Ryzen 7 5700G with Radeon Graphics Memory: 32 GiB of RAM (31.1 GiB usable) Graphics Processor: NVIDIA GeForce GTX 1660 SUPER Manufacturer: ASUS ADDITIONAL INFORMATION - System Tray must not have been opened before. - Notification Icon must *not* be on Panel on login. - After plasmashell freeze, Desktop still works. I was able to start KRunner and Kitty+btop to confirm the memory leak. - Attached image is photo of screen *after* system-freeze/kernel panic. RAM allocation history and plasmashell RAM use are visible.
Can reproduce exactly as described. More condensed steps to reproduce: 1. Ensure the Notifications widget is set to "Shown when relevant", and restart plasmashell for good measure 2. Configure System Tray > set Notifications widget to "Always shown" and click OK 3. Click Notifications widget in System Tray 4. Click Back button in its header Backtrace of what it's doing when the memory usage skyrockets: #0 __memset_avx512_unaligned_erms () at ../sysdeps/x86_64/multiarch/memset-vec-unaligned-erms.S:210 #1 0x00007fe6ce9c2afc in memset (__dest=<optimized out>, __ch=0, __len=96, __dest=<optimized out>, __ch=<optimized out>, __len=<optimized out>) at /usr/include/bits/string_fortified.h:59 #2 QV4::MemoryManager::allocData (this=0x565408985680, size=96) at /usr/src/debug/qt6-declarative/qtdeclarative/src/qml/memory/qv4mm.cpp:1012 #3 0x00007fe6ce954761 in QV4::MemoryManager::allocateObject<QV4::QObjectMethod> (this=0x565408985680, ic=<optimized out>) at /usr/src/debug/qt6-declarative/qtdeclarative/src/qml/jsruntime/qv4qobjectwrapper_p.h:371 #4 QV4::MemoryManager::allocateObject<QV4::QObjectMethod> (this=0x565408985680, ic=0x7fe69ea3c700) at /usr/src/debug/qt6-declarative/qtdeclarative/src/qml/memory/qv4mm_p.h:270 #5 QV4::MemoryManager::allocateObject<QV4::QObjectMethod> (this=0x565408985680) at /usr/src/debug/qt6-declarative/qtdeclarative/src/qml/memory/qv4mm_p.h:280 #6 QV4::MemoryManager::allocate<QV4::QObjectMethod, QV4::ExecutionEngine*&, QV4::Heap::Object*&, int&> (this=0x565408985680) at /usr/src/debug/qt6-declarative/qtdeclarative/src/qml/memory/qv4mm_p.h:313 #7 QV4::QObjectMethod::create (engine=0x5654086b4330, wrapper=0x0, index=97) at /usr/src/debug/qt6-declarative/qtdeclarative/src/qml/jsruntime/qv4qobjectwrapper.cpp:2712 #8 0x00007fe6ce9454ef in QV4::QObjectWrapper::getMethodFallback (engine=0x5654086b4330, wrapper=0x7fe5dcbd2400, qobject=0x565409fcc320, name=<optimized out>, flags=...) at /usr/src/debug/qt6-declarative/qtdeclarative/src/qml/jsruntime/qv4qobjectwrapper.cpp:400 #9 0x00007fe6ce91acbf in QV4::Lookup::getterFallbackMethod (lookup=0x565409fca078, engine=0x5654086b4330, object=...) at /usr/src/debug/qt6-declarative/qtdeclarative/src/qml/jsruntime/qv4qobjectwrapper_p.h:124 #10 0x00007fe6ce9dd123 in QQmlPrivate::AOTCompiledContext::initCallObjectPropertyLookup (this=0x7ffde92753f0, index=<optimized out>, object=0x565409fcc320, relativeMethodIndex=9) at /usr/src/debug/qt6-declarative/qtdeclarative/src/qml/qml/qqml.cpp:2518 #11 0x00007fe69f724855 in ???
