I do not remember the exact version (upgrades) after which it started, but the screen flickers excessively when the screen background is white (webpages, apps, etc.). It may also flicker on darker pages, but that isn't visible to human eyes (atleast not visible to me). I'd be happy to share relevant details on demand. Thanks!
