Main window geometry issue is still unresolved.

Observed behavior on XFCE/X11:

  • MangoTune can open slightly off-screen
  • it can grow wider after page switches like Live Preview -> Debug -> Dashboard
  • X11 minimum-size hint stays the same during the width jump

Current state:

  • temporary mitigation is to start the main window near the widest observed page width so the drift is less obvious
  • lazy-page experiment did not help and was reverted

Reference:

  • full investigation notes are in docs/WINDOW_GEOMETRY_INVESTIGATION.md
