ProbeLabs65 findings · 95 requirementsA proof layer — requirements, tests and verified fixes — for two of Omarchy's subsystems: the application menu (launcher scripts, QML model, JSONC config, search and selection) and the lock screen (lock scripts, QML, PAM authentication). Scope is deliberately limited to those components of omacom/omarchy; the rest of the distribution is not covered.

Original report
System details
Omarchy 4.0.0.r1703.g78d3224-1, quickshell-git 0.3.0.r20.g28771c7-1, qt6-declarative 6.11.1-3, kernel 7.1.8-arch1-3.
GPU: AMD amdgpu (1002:699f) + Intel i915 (8086:4692), hybrid graphics.
What's wrong
Quickshell segfaults while delivering a synthesized context-menu event (right-click/long-press). It crashed, wrote a crash report, and auto-restarted itself within the same second — no data loss, but the shell UI drops and rebuilds.
Backtrace (from Quickshell's own crash report, matches coredumpctl)
#0 QQuickItem::mapToScene(QPointF const&) const — crash, libQt6Quick.so.6
#1 QQuickDeliveryAgentPrivate::contextMenuTargets(QQuickItem*, QContextMenuEvent const*) const
#2 QQuickDeliveryAgentPrivate::deliverContextMenuEvent(QContextMenuEvent*)
#3 QQuickDeliveryAgent::event(QEvent*)
#4 QQuickWindow::event(QEvent*)
#5 QCoreApplication::notifyInternal2(QObject*, QEvent*)
#6 QWindowPrivate::maybeSynthesizeContextMenuEvent(QMouseEvent*)
#7 QQuickWindow::event(QEvent*)
#8 QCoreApplication::notifyInternal2(QObject*, QEvent*)
#9 QGuiApplicationPrivate::processMouseEvent(...)
...
qs::launch::launch(...) at src/launch/launch.cpp:320contextMenuTargets walks a QQuickItem's parent chain calling mapToScene() on each; a segfault here is consistent with a dangling/already-destroyed item in that chain at the moment the context-menu event was delivered.
Steps to reproduce
Not reliably reproducible yet — happened once, triggered by a right-click/long-press somewhere in the shell UI. Will update if a reliable repro is found.
Notes
This is one of five Quickshell crashes on this machine in the past 9 days; the other four are SIGABRT in an unrelated QML hot-reload/teardown path and appear to be a separate issue.
