Sentry Crash Report:

Description gje968 2016-01-22 12:11:50 UTC 
Application: kwin_x11 (5.4.2)

Qt Version: 5.4.2
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:
Navigating to a youtube HTML5 video: if Chrome is in fullscreen, it always happens. If Chrome is not, it only sometimes happens.

- Custom settings of the application:
I use the Diamond desktop them, the breeze-hacked cursors, and breeze loock & feel as well as spladch screen. I also use the following desktop effects: window blur at 50%, mouse click animation, background contrast, fade, glide, login, logout, maximize, sliding popups, translucency (10, 8, 10, 10, 10, disabled), window aperture, wobbly windows (8, 75, 10), minimize animation, dialog parent, dim screen for administrator mode, slide, desktop grid, and present windows.

The crash can be reproduced every time.

-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault

Comment 1 Thomas Lübking 2016-01-22 12:25:32 UTC 
Driver bug, induced by QtQuick as used by the aurorae decoration engine.
The crashes should not occur with the breeze decoration.

It looks a hell lot like https://bugreports.qt.io/browse/QTBUG-50368, but that's about inactive X screens - is this on bare metal or some virtual machine, vnc etc.?

Also check whether all backtraces follow the same pattern or this may be a red herring on bug #352259.
Comment 2 gje968 2016-01-24 01:43:45 UTC 
This is a completely native installation. Is there an update to aurorae or something that fixes this?
Comment 3 Thomas Lübking 2016-01-24 09:06:55 UTC 
If the presented backtrace is legit (ie. they all look like this and this is not the result from some stack corruption, check other backtraces) the bug is in the nvidia driver, triggered by QtQuick. The arorae decoration can never workaround/fix/avoid it (execpt by dropping QtQuick as backend)

Because of the specific conditions, can you please attach the output of "qdbus org.kde.KWin /KWin supportInformation"
Comment 4 gje968 2016-01-24 23:27:54 UTC 
FYI I'm using a GTX 960.
Output of "qdbus org.kde.KWin /KWin supportInformation": https://paste.kde.org/pfa68qbgi
Comment 5 Thomas Lübking 2016-01-24 23:45:51 UTC 
> unredirectFullscreen: false
Nope.

btw, please leave the bug state as it is - whether the bug is in the nvidia blob or QtQuick - it's not in the aurorae engine (or any kwin)

As mentioned, resort to the breeze decoration to prevent running into this.
Comment 6 gje968 2016-01-25 00:06:23 UTC 
I actually haven't moved it, that's where DrKonqui put it.

I don't see either of those under "component", and selecting qtcurve as the product (there is nothing for nvidia) still leaves only aurorae as the component. (I've never used this website before; can you tell? lol)
Comment 7 Thomas Lübking 2016-01-25 00:55:58 UTC 
I meant the "resolved/upstream" condition - you kept reverting it to "unconfirmed"
Maybe mousewheel and stupid browser?
Could happen if wheeling over the "resolved" combobox alters it instead of scrolling the page - *shrug*
Comment 8 gje968 2016-01-26 22:25:49 UTC 
Yea, probably. I didn't even notice that thing. I can confirm this doesn't happen with the Breeze theme, but I really don't like the way it looks. Do all themes I download use QtQuick? Is there any way to tell if a theme uses QtQuick or not?
Comment 9 Thomas Lübking 2016-01-26 22:29:03 UTC 
(In reply to superrobowizard from comment #8)
> Do all themes I download use QtQuick?
Yes, sorry.
You can alter the size of the breeze deco (and some other things, run "breeze-settings5")
Comment 10 gje968 2016-01-27 00:50:49 UTC 
So I'm stuck with a theme I don't like or a theme that crashes my window manager occasionally. This doesn't sound like a good deal to me.
Does only the desktop theme matter, only the window borders matter, or both?
Comment 11 Thomas Lübking 2016-01-27 09:22:41 UTC 
It's a qtquick related issue and will affect at least all aurorae themes (and most likely the Plastik decoration as well) no matter of any further settings.
