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.r2186.gee8ebf6-1
What's wrong?
Description
While holding Ctrl and a repeatable key, the first few key-down events reach the application with Ctrl held, but subsequent repeated key-down events arrive without Ctrl. For example, holding Ctrl+W changes from Ctrl+W events to plain W events even though Ctrl remains physically pressed. This affects native Wayland applications, including Firefox and Visual Studio Code. The same keyboard behavior worked as expected under KWin Wayland.
Steps to reproduce
- Start an Omarchy session with
omarchy-fcitx5.servicerunning. - In a native Wayland application, hold Ctrl and a repeatable key long enough for keyboard repeat to begin. Observe the modifier state on the repeated key events.
- Temporarily stop fcitx5 with
systemctl --user stop omarchy-fcitx5.serviceand repeat the test. - Restore the service with
systemctl --user start omarchy-fcitx5.service.
Expected behavior
Ctrl remains active on every repeated key event until the physical Ctrl key is released.
Actual behavior
After a few repeated key-down events, the application sees the key without Ctrl. I manually confirmed that the problem disappears when omarchy-fcitx5.service is stopped.

- Omarchy #5598: fcitx5 prevents modifiers held on one keyboard from applying to keys on another in native Wayland apps; stopping fcitx5 resolves it. This is a related modifier-state failure, though the reproduction differs.
- Hyprland discussion #9954: tracks multi-keyboard modifier handling and the fcitx5 input-method path.
The precise point where the Ctrl state is lost still needs a Wayland keyboard event trace. The stop/start comparison isolates fcitx5 as a necessary part of this reproduction.
