At the end of 2021, Microsoft acknowledged an issue preventing image editing apps from rendering colors correctly on specific HDR displays. The company has released a fix for the problem that's making its way to Windows Insiders on the Beta and Release channel.
There's a massive list of new stuff coming to Windows 11 in this update, but most of them are all minor bug fixes. The one that will impact the most users is the fix for the HDR issue. The issue primarily caused white colors to display bright yellow or other colors. Because the issue occurred in imaging editing software, this was a considerable problem as color accuracy is essential when working with images.
One of the other fixes includes improved reliability of application installations on ARM64 devices and an issue that causes ARM64 devices to stop responding when they hibernate or wake from hibernation. Basically, if you're running Windows 11 on an ARM chip, you'll notice some substantial improvements.
Other fixes include repairing an issue that affected predictive pre-rendering in Microsoft Edge Internet Explorer mode, tweaking a problem that causes the audio service to stop responding on some devices that support hardware-accelerated Bluetooth audio, and plenty of other stuff.
You can read the full patch notes in Microsoft's blog post if you want to see everything coming to Windows 11 soon. Since this update is in the Release and Beta channels, they'll make their way to the final Windows 11 build shortly.
