This causes windows to automatically scale the game window size up if the user has set their system to high-dpi mode. The game window is then much larger than the screen size, with most of the content pushed off-screen. Setting this up correctly is just a matter of calling an API function to tell windows not to do that, although you should then scale up the game content to match the user's DPI choice. As a workaround, the user can right-click on the cogmind executable and choose 'Disable display scaling on High-DPI systems' in the compatibility tab (I may be misremembering the wording there; I'm not right in front of a windows computer at the moment.)
