Yes, it’s in my game .exe’s manifest. I deleted the entry and set “Generate Manifest” to NO. Looks like it works. Hope it does not have any side effects.
You may want a manifest if your application is high DPI aware. The best way to set high DPI awareness is through the manifest, but you can always write it yourself and don’t even have to embed it. Although there are also functions (SetProcessDPIAware and SetProcessDpiAwareness) that can be called at runtime even though their use is discouraged.
If you don’t know what high DPI awareness is: If an application that is designed with pixels in mind is displayed on a screen with very small pixels, it would be very hard to read. To ensure compatibility, Windows will transparently scale the application up (probably with a bilinear filter). There’s some blurriness with that which can be avoided by telling Windows that your application is high DPI aware.
