Application: kwin_x11 (5.3.0)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-15-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
- What I was doing when the application crashed:
Changing location and orientation of 2 different monitors.
- Unusual behavior I noticed:
When setting new positition for my second monitor, if I move the monitor and rotate it, then it will rotate itself back when I apply. To make the monitor stay in the proper orientation, I must move the monitor to the side I want, apply, rotate, apply, then move it again to be next to my main monitor.

-- Backtrace:
Application: KWin (kwin_x11), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
