Custom cursor not resetting

Godot Version

4.3 (latest steam release)

Question

Input.set_custom_mouse_cursor(null) isn’t resetting my cursor.

I’ve ensured the code that initially changes the cursor to a sprite isn’t being called after the cursor is reset, that isn’t happening.

Tried two separate projects and two separate operating systems.
Works on Windows but not on Linux.

Instead of setting it to null you could explicitly set it too CURSOR_ARROW which is the default? Would that work?
