Title:
  GTK context menu freezes when opening submenu near screen edges in
  Ubuntu 25.10 beta

Status in gtk4 package in Ubuntu:
  Confirmed
Status in mutter package in Ubuntu:
  Confirmed
Status in nautilus package in Ubuntu:
  Invalid

Bug description:
  While testing Ubuntu 25.10 beta, I noticed that enabling display
  scaling (for example, setting the scale to 200%) causes issues with
  Nautilus context menus.

  Steps to reproduce:

  1. Enable fractional scaling (e.g., 200%) in Display Settings.
  2. Open Nautilus and right-click on a file or folder.
  3. The context menu appears but becomes frozen. It does not respond to input until I click outside the Nautilus window, at which point it closes.

  This is particularly noticeable when using **Nautilus Scripts**. The
  context menu freezes every time I try to access my custom scripts.

  Expected behavior:
  The context menu should remain responsive and allow interaction with its items, regardless of display scaling settings.

  Actual behavior:
  The context menu becomes frozen/unresponsive whenever display scaling is active.

  Additional notes:

  * This issue only occurs when scaling is enabled (e.g., 200%).
  * I suspect the bug may be related to underlying **GNOME or GTK libraries** rather than Nautilus itself.
  * System tested on: Ubuntu 25.10 beta (fresh install, updated).
