Cursor not showing in "Save changes?" dialog when closing the app

[GeertJohan]

Lorien version: 0.6.0 release from github for Linux

OS/device including version: Linux Ubuntu 22.04.3 LTS with X11, LightDM (display manager) and xmonad (window manager). Nvidia graphics drivers.

Issue description: The cursor disappears over the "Save changes?" when closing the application. In other dialogs (save file) I get my default system cursor (the dark mode variant, which is nice).

Steps to reproduce: Exit, then hover mouse over the "Save changes?" dialog.
