            Bug ID: 384250
           Summary: PlasmaShell and systemsettings crash on Intel GPU 530
           Product: systemsettings
           Version: 5.10.5
          Platform: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: plasma-bugs@kde.org
          Reporter: mistry01@gmail.com
  Target Milestone: ---

Application: systemsettings5 (5.10.5)

Qt Version: 5.7.1
Frameworks Version: 5.37.0
Operating System: Linux 4.10.0-33-generic x86_64
Distribution: Ubuntu 17.04

-- Information about the crash:
- What I was doing when the application crashed:
Scrolling in kwin_X11.

- Unusual behavior I noticed:
Plasmashell crashes.  All window elements drawn in the same  small area
overlapping in Qt apps (window area draws every element at 0,0 such as
systemsettings Desktop Themes).

The reproducible crash is when I scroll using libinput from a Logitech G700s
mouse.  If you go against the scroll direction, such as scolling down fast and
then switching direction, kwin_x11 crashes.  SDDM does not launch.  Had to
switch to lightDm and LXQT running kwin_x11 for current functionality.

Main failure reported in dmesg: 
plasmashell[6514]: segfault at 55c4efbdafc0 ip 00007f77c403f450 sp
00007ffef75c85b0 error 4 in libqquicklayoutsplugin.so[7f77c4030000+1c000]
[  454.466680] systemsettings5[23828]: segfault at 5599c1ac78d0 ip
00007f6d1c07a450 sp 00007ffd9fa97230 error 4 in
libqquicklayoutsplugin.so[7f6d1c06b000+1c000]


- Custom settings of the application:
-> I have Intel GPU 530.  Used modesetting, next intel drivers. UXA and SNA
accel attempted as well.
-> Kernel parameters: nogpumanager
blacklist=nouveau,nvidiafb,nvidia-modeset,nvidia-uvm,nvidia,nvidia-384 acpi=!
acpi_osi=\"Windows 2009\" intel_iommu=igfx_off i915.enable_fbc=1
i915.powersave=1 i915.enable_rc6=1
->

The crash can be reproduced every time.
