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
