Accessibility: Cursor Size Inconsistency - System Settings Ignored

When adjusting cursor size via system settings in GNOME or KDE, Qt applications fail to respect the configured size. The cursor reverts to its default size when hovering over Qt app windows, though restarting the application temporarily enforces the system settings.

Steps to Reproduce:
1. Configure cursor size:

• GNOME: Settings > Accessibility > Cursor Size
• KDE: System Settings > Color & Schemes > Cursors
  2. Open a Qt (Widget/Quick) application
  3. Observe cursor behabior:
• The cursor size changes to the system-configured size outside Qt apps.
• Cursor size reverts to default (smaller) when hovering over Qt app windows.
  4. Workaround: Restart the Qt application to temporarily enforce the system cursor size.

Expected Result:
Cursor size should respect to the system configuration

Actual Result:
Cursor size reverts to default in Qt applications unless the app is restarted.
