Application: plasmashell (5.5.3)

Qt Version: 5.5.1
Operating System: Linux 4.2.0-25-generic x86_64
Distribution: Ubuntu 15.10

-- Information about the crash:
- What I was doing when the application crashed:
I clicked on menu launcher (Dashboard) and plasma crashed
- Unusual behavior I noticed:
It seems there is problem with compositing, with EGL the screen sometimes does not refresh and with XGL it flickers, only way is to use XRender.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
