Package: kwin-x11 Version: 4:5.7.0-1 Followup-For: Bug #834359 Dear KDE Team,
Please find below information from KDE crash reporting assistant. The crash happens occasionally soon after new windoe is created. I suppose the application is irrelevant, as I spotted this crash starting either a webbrowser as an uxterm or gitk. The usual scenario of crash is that new windows appear, then kwin crashes. I didn't do a proper measurements neither trying to reproduce the problem on purpose, however I would estimate the crash happenes approximately once per 20 starts. Please note there is https://bugs.kde.org/show_bug.cgi?id=361236 already reported in upstream.
