Application: kwin_x11 (5.8.5)

Qt Version: 5.6.1
Frameworks Version: 5.28.0
Operating System: Linux 4.4.0-59-generic x86_64
Distribution: Linux Mint 18 Sarah

-- Information about the crash:
- What I was doing when the application crashed:
Booting system.

- Unusual behavior I noticed:
Some startap applications behave oddly.
Eg. Yakuake starts before plasma desktop itself and stays open until manualy closed ( hid).

-- Backtrace:
Application: К‑вин (kwin_x11), signal: Segmentation fault
