Description mhruscak 2016-09-20 07:55:21 UTC 
If panel is created on second connected monitor, it leads to immediate freeze of whole system, not only plasmashell. Mouse and keyboard become unresponsive for many 0.5-2.0sec long periods.
Need to mention, that it only happen if I trying to add Default panel. Empty panel is ok though.
Helps only killing plasmashell.


Reproducible: Always

Steps to Reproduce:
1. install KDE
2. connect second display
3. slightly change default panel(add new widget) on first display
4. try to create "Default" panel on second monitor

Actual Results:  
Many freezes, system unresponsive

Expected Results:  
Panel should be created

Same happens if system is powered-off with 2 displays connected and then turned on with only one connected. Second panel jumps to first monitor and freezes.

Does this happen every time?

Can you run from a konsole

gdb plasmashell

then when it freezes alt+tab to konsole
press control+C and then type "bt" and copy and paste here.

We do have one open bug from a similar cause, I'd like to check it's the same.

Unfortunately no, because I have switched back to KDE4 meanwhile.

Then we've got nowhere to go from here.
