Omarchy
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 4.0.3-1
What's wrong?
When i was asking certain_browser ai about my problems, i sent a snippet of process logs as a context for prompt. It appears that certain_browser ai populates address bar AND tab (window) title with the prompt you're sending to an ai.
It seems like fcitx5 tried to handle the message but it got title length larger than its capacity (Message length 4120 exceeds limit 4096; WARN: The Wayland connection experienced a fatal error: Argument list too long) so it dies immediately (fcitx5[20769]: E2026-09-10 08:04:13.145495 waylandeventreader.cpp:129] Wayland connection got error: 7).
omarchy-shell tries to restart itself several times, but fails unless you switch the tab, obviously.
