Comment (by SirBogman):

 I made a local build of SDL 2.30.0 that fixes the issue almost completely.
 The one exception is that I know of is, if you take a screenshot with
 cmd+shift+4, then the system cursor is visible until you move them mouse
 (I'm ok with this).

 ScummVM is constantly calling SDL_ShowCursor(0), when the mouse moves, to
 hide the cursor.

 In the implementation of SDL_ShowCursor, if the desired state (visible or
 not) matches the state cached in SDL_Mouse::cursor_shown, then nothing is
 done. The problem is that the state of SDL_Mouse::cursor_shown can get out
 of sync with the actual state of the system cursor visibility. If I remove
 the comparison to the cached state and just always update the cursor
 visibility, then it works. I'll look into whether I can fix this in a way
 that is appropriate for submission to the SDL library.
