Description Luiz Angelo De Luca 2014-10-15 20:12:08 UTC 
Hello,

Kwin crashed twice in sequence after I changed the screen settings in systemsettings:
In both cases, the BT is the same (except for memaddr):

Comment 1 Luiz Angelo De Luca 2014-10-15 20:14:19 UTC 
Related to Bug 340004.

I'm using kde5 packages from OpenSuSE OBS
Comment 2 Thomas Lübking 2014-10-15 20:34:04 UTC 
Did you get rid of the framebuffer console?
Otherwise (and for the particular context and other bug) this could be related to https://bugreports.qt-project.org/browse/QTBUG-39996

*** This bug has been marked as a duplicate of bug 337016 ***
Comment 3 Luiz Angelo De Luca 2014-10-15 20:40:28 UTC 
Yes, no framebuffer console. Text only. And it seems to be related.
BTW, compositing is enabled
