Observed runtime output (not app UI)
Linux x86_64 / Electron 44.10.1 / X11 / 1280x800
Fresh HOME, XDG config and T3 home; no seeded data.

1. Launch real bundled Electron; wait for backend ready.
2. Wait 15 seconds; capture two identical frames 500ms apart.
3. Record 5 seconds, then terminate the private Xvfb.

Electron launcher exit status: 1
Main exited 0.074s after display termination began.
GPU stderr: X connection error received.
Observed descendants before display loss: 6
Descendant states at main exit: {"108652": "gone", "108653": "gone", "108702": "R", "108710": "S", "108772": "S", "108825": "S"}
Desktop lifecycle trace names:
  desktop.lifecycle.register
No exit trace; no beforeQuit/windowAllClosed/shutdown trace.
No desktop log entry explaining the main-process exit.
