Delphi 10 Seattle Update1 fixed this error: Additional DPI support for the IDE (see http://edn.embarcadero.com/article/44619 ) I installed it on Windows 10 64 bit. My screen resolution: 3840 * 2160. but the IDE is not supported, texts and objects are blurry.
Edit
After I edited this manifest and set the dpi value to true (see screenshots), it worked, but not completely. Instead of using this manifest, we can check the "display scaling with the screen diagonal when setting high density" in the application properties. In fact, this manifest makes these settings no more. see my screenshots.
