Hi, kwin always crashes when an OSD pop-up is displayed to notify the user that the touchpad has been switched on or off. Here is how to reproduce this crash: * if your laptop has a key to activate or deactivate the touchpad, use this key * if not: - turn on this setting: Input Devices -> Touchpad -> Enable/Disable Touchpad -> Disable touchpad when mouse is plugged in - plug a mouse This is with Neon packages as of today: Package: kwin-x11 Version: 4:5.8.4+p16.04+git20161225.1132-0
Created attachment 102995 [details] Backtrace screenshot Getting a backtrace is difficult because: 1. drkonqi does not display anything useful 2. a crash file is created in /var/crash/ and I do not know how to extract information from this file. I tried to get a backtrace by attaching gdb to the kwin_x11 process before the crash but I got nothing this way. The best I could do is a screenshot from apport with the full backtrace, so here it is.

Quite sure it's the same issue *** This bug has been marked as a duplicate of bug 374038 ***
I confirm that sound OSD also crashes kwin therefore this is the same bug.
