Your codedump lacks debug symbols but we can see the culprit nonetheless: #2 0x00007fc93a28dda5 _ZN9QtWayland9wl_output15handle_geometryEPvP9wl_outputiiiiiPKcS5_i (libQt5WaylandClient.so.5 + 0xb6da5) I suspect a newer version of Qt would help. Was this fixed in Qt 5.15.3 or something? Or with the KDE patch collection? I just checked qt5 repo and site. The v5.15.3 and future v5.15.4 are commercial-only. I do not have access to them and v6.x.y are not yet in gentoo repo KDE patchset are in https://invent.kde.org/qt/qt/qtbase/-/tree/5.15 ? Yep, all the repos in https://invent.kde.org/qt. I'm looking for info and it seems to be an old bug, did not find how to fix it yet: https://bugreports.qt.io/browse/QTBUG-62044 https://bugzilla.redhat.com/show_bug.cgi?id=1945992 https://www.mail-archive.com/kde-bugs-dist@kde.org/msg434546.html Qt 5.15 stable branch ebuilds (5.15.9999) are available in Gentoo's qt overlay and they are pulling from KDE's kde/5.15 branch for some time already. https://gitweb.gentoo.org/proj/qt.git/ Just tried this overlay, issue is still here. If i plug another screen a lot of things segfault and desktop becomes unusable, still caused by handle_geometry. inline:
