Comment (by criezy):

 To clarify, all the issues reported here are specific to platforms using
 SDL1 and with both the OpenGL and SurfaceSDL backends. With those, the
 filtering is indeed only available for the OpenGL graphics mode.

 The comment from bgK on the other is correct when using SDL2, or at least
 was correct at the time of writing. Since then we have added the
 possibility to resize non-OpenGL windows as well, which means the
 filtering is now used in fullscreen mode, and in windowed mode (when
 manually resizing the window) for both OpenGL and non-OpenGL graphics
 mode. And that means the filtering option is always visible and always
 enabled.

 Fixing the described issues is not easy to do. If somebody can come up
 with an implementation that works while not breaking other use case, then
 this might be accepted. But since SDL1.2 is now obsolete and SDL2 is the
 default when building ScummVM (and for releases), the issue should
 disappear by itself anyway as we phase out SDL 1.2.
