Omarchy

ProbeLabs65 findings · 95 requirements

A 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

Quickshell SIGSEGV (stack overflow) when opening paste history if a copied HTML page is in the clipboardrevision 1 · captured 2026-09-28 21:24 UTC via poll

Problem

Opening the paste-history overlay (Super+CTRL+V) reproducibly crashes the shell (quickshell 0.3.1 / Qt 6.11.2 / Omarchy 4.0.1) with SIGSEGV whenever the clipboard history contains an HTML entry — e.g. a copied web page.

Repro

  1. Copy any HTML body (e.g. select-all and copy a <body …> from a web page).
  2. Open Paste History (Super+CTRL+V).
  3. The shell crashes with SIGSEGV (and would crash-loop if kept open).

Root cause

The crashing Text elements in shell/plugins/clipboard/Clipboard.qml (Clipboard.qml:502 row preview and Clipboard.qml:548 detail pane) use Qt's default textFormat: Text.AutoText. Because a copied string can start with <body …>, AutoText treats it as rich text and hands it to Qt's StyledText engine. The log shows these messages immediately before the crash:

qt.quick.styledtext: StyledText - Invalid base url in img tag
qt.quick.styledtext: StyledText doesn't support entity "&b.addEventListener?b.addEventListener(c,d,!1):..."

Laying out a large rich-text document (one cloned body here was 235 KB with 6 <img> and 3 <script> tags) inside the ListView/Flickable while the layer-shell panel window is being configured by the compositor drives a reentrant geometry/binding loop that never terminates:

QQuickTextPrivate::updateLayout
QQuickText::geometryChange
QQuickItem::setWidth
QPropertyBindingData::notifyObserver_helper
QPropertyBindingPrivate::evaluateRecursive
QQmlPropertyBindingJS::expressionChanged
QWaylandWindow::resizeFromApplyConfigure   <- wayland configure

~30+ nested repeats of that cycle → stack overflow → quickshell's crash handler raises SIGSEGV (si_code SI_TKILL).

Suggested fix

Set textFormat: Text.PlainText on those two Text elements so clipboard content is never rendered/parsed as rich HTML. A clipboard picker should not interpret pasted content as markup — this also closes a script/entity-injection surface in the preview.

## Problem

Opening the paste-history overlay (Super+CTRL+V) reproducibly crashes the shell (quickshell 0.3.1 / Qt 6.11.2 / Omarchy 4.0.1) with SIGSEGV whenever the clipboard history contains an **HTML** entry — e.g. a copied web page.

## Repro

1. Copy any HTML body (e.g. select-all and copy a `<body …>` from a web page).
2. Open Paste History (Super+CTRL+V).
3. The shell crashes with SIGSEGV (and would crash-loop if kept open).

## Root cause

The crashing `Text` elements in `shell/plugins/clipboard/Clipboard.qml` (`Clipboard.qml:502` row preview and `Clipboard.qml:548` detail pane) use Qt's default `textFormat: Text.AutoText`. Because a copied string can start with `<body …>`, AutoText treats it as rich text and hands it to Qt's `StyledText` engine. The log shows these messages immediately before the crash:

```
qt.quick.styledtext: StyledText - Invalid base url in img tag
qt.quick.styledtext: StyledText doesn't support entity "&b.addEventListener?b.addEventListener(c,d,!1):..."
```

Laying out a large rich-text document (one cloned body here was 235 KB with 6 `<img>` and 3 `<script>` tags) inside the `ListView`/`Flickable` while the layer-shell panel window is being configured by the compositor drives a reentrant geometry/binding loop that never terminates:

```
QQuickTextPrivate::updateLayout
QQuickText::geometryChange
QQuickItem::setWidth
QPropertyBindingData::notifyObserver_helper
QPropertyBindingPrivate::evaluateRecursive
