Steps to reproduce:

use it and you'll experience very annoying random crashes.
kf5 is NOT stable enough IMHO and I hope that it won't take yeas to reach a decent stability like as for Kde4.

Plasma 5.5 crashes some times in a day. And plasma 5.5 hangs after one-two days without reboot. KDE developers says that is Xorg bug, but I don't care who is bad worker: I have to work with this system, you say @plasma 5.5 stable enough.
Comment by Jamp (jamp) - Tuesday, 12 January 2016, 10:00 GMT
The crashes are more frequent when the system tray is used. I am using the desktop version of telegram and often the plasmashell crashes on opening/closing the chat window.
Even more problems arise when an external monitor is used. It happens that when the external monitor is atteched/detached, the plasmashell (or even the entire desktop) crash..
With kde4 i had absolutely no problems while with kf5 i have 20/30 plasmashell crashes a day.
I have two different laptops both with arch and kde and both have more or less the same problems.

I divide system try and Program List on my desktop. Plasma crashes when I'm looking to the program list to see activity.

Only two persons do have this problem ?
After some qt/kde upgrades I still get this error many many times a day...
The problem arises when something changes in the taskbar or in the tray.
In particular closing one or more windows can trigger the bug.
This is very inconvenient because I cannot use my notebook, e.g., to show
slides with a projector, and is very annoying also in the normal use.

experienced a few minutes ago.. The inteface totally locked up as the window manager crashed without notice..
I had to restart SDDM and lost all work...

Any development to solve this issue?

Plasma still hangs on a next day of work. And it crashed on task manager panel shows and hide.

Finally solved by dumping KDE

Can someone still reproduce this with a recent Plasma/Qt?

No, I will close this bug.
