Although Microsoft has apparently fixed the issue with a recent Windows update, according to some users, this does not resolve the issue, but luckily, there still seems to be a workaround that can be used. The issue itself, documented on the Nvidia forums, Reddit, and also addressed by monitor maker Eizo (known for its high-end displays), means that colors are not rendered correctly with banding (vertical lines) in color gradients. color. Eizo said: "Notice: We strongly recommend that you do not use a PC running Microsoft Windows 10 (1903) (Updated May 2019), especially for creating diagnostic images or Graphics Editing that require pitch precision. The gremlin seems to be obvious for some GPUs, however, as mentioned, with the recent patch KB4501375 for Windows 10 May 2019 Update, Microsoft claimed that the color management issue was resolved. In the release notes, Microsoft said: " This issue can cause the pilot, color management profiles, or gamma correction to stop after a "device" shutdown. However, at least reviewing some of the users posting on the Nvidia forum, the issue is not really resolved by the fix. But as mentioned, there is a workaround that seems to do the trick, and it can be activated from the task scheduler.
