Microsoft has confirmed a bug that’s causing rendering issues with HDR displays in Windows 11.
It’s said the apps using Win32 API for rendering colors are affected, as they don’t perform as expected. As they’re returning unexpected errors, Microsoft recognized the issue and is now working on a fix, which may come in late January next year.
Windows 11 HDR Display Issue
As more and more users are now demanding a quality output from things they buy, display OEMs are fitting HDR (High Dynamic Range) as an option for a rich viewing experience. These HDR displays produce more vivid colors as they have an increased range of colors, thus supporting a wider color gamut.
As they’re generally better than Standard Dynamic Range (SDR), people are preferring to view and work on content in HDR, for a rich experience. But, it’s seen that system displays using Windows 11 OS are facing problems in serving HDR content.
Many reports have surfaced pointing at the broken color rendering in apps, that are using Win32 APIs. As Microsoft noted in its Windows Health Dashboard, “After installing Windows 11, some image editing programs might not render colors correctly on certain HDR displays.”
Further, “This is frequently observed with white colors, which could display in bright yellow or other colors. This issue occurs when certain color-rendering Win32 APIs return unexpected information or errors under specific conditions.”
As they’ve identified the issue, they’re now working on a fix that may come in late January 2022. Until then, Microsoft specified the Windows 11 HDR page for solving known issues if any. Also, it stated that not all the profile management programs are impacted by this bug, pointing at color profile options in Windows 11 Settings page working just fine.
