Hi lapaev, I don't believe that is going to work for MoI's particular case because that requires some special setup at the host process level to make that happen, and some of the difficulty is in getting the MoI main process to be set up as high resolution aware so that its main window at the operating system level is not made half size and then scaled up.

That CSS stuff that you're showing works in Safari for example because Safari as a whole is set up as high resolution aware.
