Description Vadym Krevs 2010-10-18 18:53:57 UTC

Application: kwin (4.5.2 (KDE 4.5.2) "release 10")
KDE Platform Version: 4.5.2 (KDE 4.5.2) "release 10"
Qt Version: 4.6.3
Operating System: Linux 2.6.34.7-0.4-desktop x86_64
Distribution: "openSUSE 11.3 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:

Got a new desktop today with an NVDIA GeForce 310 card. Moved the harddrive from the old desktop (which had a NVIDIA GeForce 7600 GS) into the new machine. Binary NVIDIA driver was already installed (260.19.04) and worked faultlessly. Desktop effects were off. Everything was fine. Attempted to enable desktop effects. LOgged off and logged back on. Now kwin seems to crash on login.

The crash can be reproduced some of the time.

Comment 1 Martin Flöser 2010-10-18 18:58:57 UTC

The crash is caused by the sharpen effect. I recommend to disable this effect 
as you do not need it for NVIDIA cards and it has a significant penality hit.

Comment 2 Helder Meneses 2010-10-28 19:24:03 UTC

Hi there,

i have this problem and now i cant do anything with my computer...

i dont have effects enable, and it crash...

when will the KDE be stable enough to work daily basis? it's like a never ending story for users...

put kde stable ... and when using the word stable, is like no errors...

sad...

Comment 3 Christoph Feck 2010-10-28 20:47:48 UTC

Helder, please file a new bug report with the backtrace you get, it might be a completely different bug you are seeing.

Comment 5 Martin Flöser 2011-05-07 10:19:56 UTC

This should have been fixed with:

Git commit 505f7cc14a7ee9914a7d75128e28476ead34b9e0 by Thomas Lübking.
Committed on 19/04/2011 at 02:41.
Pushed by luebking into branch 'KDE/4.6'.

Validate/check logarry in lanczos filter

this will *probably* fix the mysterious __cxa_rethrow bug
we still need validation from someone encountering the bug
