--- Comment #4 from Matt Fagnani <matt.fagn...@bell.net> --- Created attachment 164390 --> https://bugs.kde.org/attachment.cgi?id=164390&action=edit Valgrind log from trying to reproduce plasmashell crash by hovering over task manager icons I saw plasmashell crash with this type of trace in Plasma 5.90.0 when I disabled WiFi in the Plasma NetworkManager applet then clicked off of the applet to close it. This crash didn't usually happen when doing so. I ran plasmashell under valgrind and reproduced the crash as before. The error The Wayland connection broke. Did the Wayland compositor die? was shown in Konsole so the crash might've been due to that different reason. The window previews for konsole and other running programs weren't shown when run under valgrind, but the popups with just their names were shown. There were many invalid reads which looked to be buffer overreads. The ones involving KSvg::SvgPrivate::createRenderer might be more likely to be involved with the window preview popups. I'm attaching the valgrind log. ==8941== Invalid read of size 16 ==8941== at 0x72310E7: UnknownInlinedFun (emmintrin.h:706) ==8941== by 0x72310E7: aeshash128_lt16 (qhash.cpp:630) ==8941== by
