[Bug]: System cursor rendered on top of game cursor on macOS

[Bouke]

Version of OpenTTD

12.2, macOS Monterey 12.5

Expected result

The game should always hide the system's cursor.

Actual result

Sometimes the system's cursor is rendered over the game's cursor.

Steps to reproduce

1. Enter Full Screen
2. Move cursor to the bottom of the screen, and move up directly (do not trigger the Dock)
3. The system's cursor is rendered over the game's cursor

Same issue here. OpenTTD 12.2, macOS Monterey 12.6. Entering full screen and then swiping to a different desktop and back will do it too.

Edit: I can reproduce this bug in 12.1, 12.0, and 1.11.2.
