I think you could bisect > between 6.4.90 and 6.6.0 though. I build from v6.4.90, it actually also crashed whenever I try to launch `env QT_PLUGIN_PATH="$(pwd)":"$QT_PLUGIN_PATH" dbus-run-session ./kwin_wayland --xwayland vkcube --wsi xlib`, however `env QT_PLUGIN_PATH="$(pwd)":"$QT_PLUGIN_PATH" dbus-run-session ./kwin_wayland --xwayland -- konsole` is fine. I also try to launch `vkcude` inside the `konsole` and it got crash as well. I am attaching the host output, konsole output and the strace to see if it is helpful. The strace log is get with `strace -f -o vkcube.strace vkcube --wsi xlib` I also run a gdb to see if it is helpful (gdb) run Starting program: /usr/bin/vkcube --wsi xlib [Thread debugging using libthread_db enabled] Using host libthread_db library "/usr/lib/libthread_db.so.1".
