Microsoft has confirmed a new issue impacting devices running Windows 11, version 21H2, where apps using Win32 APIs to render colors on some high dynamic range (HDR) displays may not work as expected.

HDR displays come with a notably increased range of color because they support a wider color gamut, resulting in more vivid colors than standard dynamic range (SDR) ones, a well as more precise colors due to added support for more color shades.
