Comment (by macca8):

 Just to advise a point of difference between macOS (with Myst3) and the
 Linux behaviour described in this ticket.

 On macOS, setting the 3D Renderer to "OpenGL with shaders", then switching
 screen modes in-game, results in an immediate crash with a segmentation
 fault. This crash doesn't occur with daily builds prior to 18 April 2021.

 With regard to using normal 3D OpenGL, switching Myst3 between screen
 modes with the "widescreen mod" engine option disabled preserves the
 screen's black borders, but the main screen and inventory items are blank
 (see attached screenshot).
 With "widescreen mod" enabled, there's no black borders and inventory
 items are hidden by default, so the result when switching is a completely
 white screen.
