            Bug ID: 349238
           Summary: kwin frequently crashes and restarts on new Fedora 22
                    upgrade
           Product: kde
           Version: unspecified
          Platform: unspecified
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: wdm8588 at gmail.com

Application: kwin_x11 (5.3.1)

Qt Version: 5.4.2
Operating System: Linux 4.0.4-303.fc22.x86_64 x86_64
Distribution: "Fedora release 22 (Twenty Two)"

-- Information about the crash:
- What I was doing when the application crashed:
When I boot into KDE Plasma since my Fedora 22 upgrade, the system is at first
unresponsive and slow.  I cannot, at first even start any application.

- Unusual behavior I noticed:
  One or several notices that kwin has crashed and restarted appear on the
screen.  However, after a few more minutes the system begins to work, albeit a
bit sluggishly.


- Custom settings of the application:
I am using an older nvidia graphics card.  Initially, after my upgrade to
Fedora 22 (from 21), KDE would not start at all, even though other window
managers would.  I changed from the nouveau drivers to the nvidia drivers and
managed to get KDE to work after disabling the "Blur" effects.  I have also
reomved the xorg libinput driver.  It seems to work a bit better without that
driver, but my testing is still inconclusive regarding that.

-- Backtrace:
Application: KWin (kwin_x11), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".
