Title: Screen Flickering Lines After One UI 7 Update (S21 Ultra)

Hi everyone,
Since updating to One UI 7, I've been seeing strange flickering lines mostly at the bottom of the screen when switching video orientations in apps like Chrome or Samsung Internet. These lines sometimes change color (white, green, black) and even show up in screen recordings, which suggests it's not a hardware or LCD issue.

I’ve already tried resetting developer settings, clearing Chrome cache, and toggling display settings like refresh rate and HW overlays, but the issue persists. Has anyone else experienced this since the update or found a fix?

Thanks in advance

The exact same situation? In that case it's definitely a software bug I hope the next security patches fix it

Samsung has been aware of this since April and has offered some phones repairs and I think yours is included look through the internet

Thank you but like I'm saying it's probably a software issue i only notice it when changing orientations and the video hasn't fully loaded yet if I wait for it to load then nothing so since it's a software thing they should fix it in updates
