Lenovo Vantage app bug turns display red in Windows 10 v1903

Windows 10 night light

Some outlets are reporting that
Windows 10 KB4512941, which is an optional update that was
shipped on August 17, also causes a red screen on some PCs.
However, the problem appears to be associated with the Lenovo
Vantage app on PCs with any version of Windows 10 May 2019
Update installed, and not the particular KB4512941 patch.

The problem has been reported by multiple users on the Lenovo
forum (1,
2,) in
the past few months. According to users, the mysterious bug
causes a red or orange tint when taking screenshots on Lenovo

This behaviour is not linked with old graphics drivers and it
only affects devices with Lenovo Vantage app. Apparently, there
are compatibility issues between Windows 10 May 2019 Update and
Lenovo Vantage app that still to be ironed out.

Lenovo Vantage is an app created specifically for PCs running
Windows 10 and it allows power users to personalize settings,
update drivers, improve performance and WiFi security.

Fortunately, there are ways to fix the problem. If you find
yourself affected by this, simply click on the ‘Reset’ button
in the Vantage app under the Night Light section. Or you can
uninstall the app and reboot your PC, and the red or orange
tint would go away. You can also try updating the app from the
Microsoft Store as it could also resolve the problem.

Microsoft and Lenovo are yet to acknowledge the bug.
