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 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 ones, a well as more precise colors due to added support for more color shades.
Customers might experience color rendering problems due to this newly acknowledged Windows 11 bug.
"After installing Windows 11, some image editing programs might not render colors correctly on certain HDR displays," Microsoft explained on the Windows Health Dashboard.
Windows 11 color profile options on the Settings page, such as the Microsoft Color Control Panel, should function correctly on affected systems.
The list of known issues addressed since Windows 11's launch in October includes an Intel audio driver bug triggering blue screens, widespread printer issues and system freezes, an issue impacting Remote Desktop, and more.
