Comment (by criezy):

 I think I finally understand what this bug report is about, and it is not
 related to HiDPI.

 The issue is when setting the scalers in the global option, and not
 overriding them for the game. In such a case with ScummVM 2.2 we do not
 apply the scaler to 640x480 games (or bigger) and display them at their
 original resolution (e.g. 640x480).

 With current master this is still the behaviour with the Normal scales,
 but not with the other scalers. For those the scalers gets applied to the
 game as well, so instead of 640x480, we get 1280x960 or 1920x1440.

 I suspect this is a regression either from the scaler plugin pull request
 or from the pull request to split the graphics modes and scalers into two
 separate popups.
 Indeed the HQ scalers do not have a 1x mode, which might be why it sticks
 with the 2x or 3x for the game as well.
