Can you reliably reproduce the crash? I was not able to reproduce it locally. What GPU and GPU drivers do you have? Can you please provide list of activated KWin effects: qdbus org.kde.kwin /Effects org.kde.kwin.Effects.loadedEffects qdbus org.kde.kwin /Effects org.kde.kwin.Effects.activeEffects The backtrace seems it could be a double-free corruption. If you can please try reproducing when running KWin under valgrind. (Note: to restart KWin, use kwin --replace. Killing KWin will usually steal you focus from console and you won't be able to start it again) I haven't been able to reproduce it either. I've tried toggling between OpenGL and XRender, and Native and Raster, and various combinations, and I haven't seen it crash again. I've also enabled and disabled the effects in the various modes and it's behaved properly. I have an Intel Haswell i7-4600U CPU with the HD Graphics 4400 GPU (this is a Lenovo T440s laptop) and an external Samsung display connected with Mini-DisplayPort to DVI-D connector. ~]$ qdbus org.kde.kwin /Effects org.kde.kwin.Effects.loadedEffects kwin4_effect_zoom kwin4_effect_login kwin4_effect_slidingpopups kwin4_effect_minimizeanimation kwin4_effect_translucency kwin4_effect_screenshot kwin4_effect_slide kwin4_effect_desktopgrid kwin4_effect_maximize kwin4_effect_fade kwin4_effect_dialogparent kwin4_effect_highlightwindow kwin4_effect_taskbarthumbnail kwin4_effect_presentwindows kwin4_effect_blur kwin4_effect_dashboard kwin4_effect_outline kwin4_effect_startupfeedback ~]$ qdbus org.kde.kwin /Effects org.kde.kwin.Effects.activeEffects kwin4_effect_blur I tried running kwin under valgrind and still no luck reproducing the problem.
valgrind --trace-children=yes \
--track-origins=yes \
--log-file=/tmp/kwin-valgrind-%p.out \
-- \
/usr/bin/kwin --replace
However, valgrind did find a number of other problems with kwin including uninitialized values, invalid writes, and invalid reads. I'll attach the valgrind logs.

This file was 940 KiB, so I compressed it with xz

since this bug cannot reproducable, i closed it as "WORKFORME". Feel free to reopen it again if you can reproduce it. I can't reproduce on RHEL 7.1, so I'm going to close this again as WORKSFORME since it only happened one time on RHEL 7.0 Alpha/Beta. |
