Description Helio Loureiro 2012-12-29 14:14:03 UTC
Application: kwin (4.9.3)
KDE Platform Version: 4.9.3
Qt Version: 4.8.3
Operating System: Linux 3.5.0-21-lowlatency x86_64
Distribution: Ubuntu 12.10

-- Information about the crash:
- What I was doing when the application crashed:
I was trying to watch a flash video via Chromium in fullscreen.

- Custom settings of the application:
Standard Ubuntu 12.10 settings and OpenGL enabled.
Screen was completely blank, without response for while.  Only after I stopped desktop effects via keyboards keybindings (<Shift>+<Alt>+<F12>), it crashed and raised an error.

The crash can be reproduced every time.

Comment 1 Thomas Lübking 2012-12-29 14:36:13 UTC
see comment #17 in the dupe - does ubuntu somehow reset the setting with every update? (it should be off by default)

Comment 2 Helio Loureiro 2012-12-29 17:29:50 UTC
What can I run to confirm that?  Or either log?
Comment 3 Helio Loureiro 2012-12-29 17:38:08 UTC
BTW it wasn't a fresh installation.  I've come upgrading since... Debian beta 4.  The last .kderc files are regarding KDE4.7 release, when I moved configuration files to .old and left KDE to create the new ones.
Comment 4 Thomas Lübking 2012-12-29 18:02:33 UTC
run "kcmshell4 kwincompositing", move to last tab and check the state of "suspend cop. for fullscreen windows"
if it's checked and was not (should not, major problem for intel drivers) someone has reactivated it and we recently got this quite often fro ubuntu 12.10 users.

so if you and all others did not activate, some distro update script will have - contact ubuntu about that aand tell them to stop doing this in case

New crash information added by DrKonqi

kwin (4.11.1) on KDE Platform 4.11.1 using Qt 4.8.2

- What I was doing when the application crashed: Kwin constanly crashes while plying fullscreen flash videos, especially when changing volume as the OSD appears it crashes.

see comment #4 - can you also please attach the output of "qdbus org.kde.kwin /KWin supportInformation" to record your gpu/driver combo?

Regarding the comment #4 that option is turned off, but I manually created a Window rule for flash plugin to suspend compositing, and it looks like that could be causing the problem ?

Comment 8 Thomas Lübking 2013-10-06 10:33:11 UTC
if the rule would apply, you could't crash in compositing as long as the flash window is there (whether another window appears and breaks the fullscreen condition doesn't matter)

the flaswindow is likely override_redirect, ie. unmanaged - you'd require scripting to have is suspend the compositor.

wild guess: set the graphicssystem to "raster" - do you still get crashes?
