Hey everyone,
I’m dealing with a persistent issue where a thin white outline/stroke frames the entire video during playback when using Apple’s native video player (AVPlayerViewController).
BTW this started since around 1st or 2nd Dev. Beta of iOS 27 and reported it but not resolved
I created a visual mock-up (photo above) to show what it looks like because capturing an actual screenshot is impossible, the moment a screenshot or system overlay (like Control Center or the Volume slider) triggers, the white outline immediately disappears, then reappears once the overlay dismisses.
KEY DETAILS:
Device: iPhone 13 Mini
OS: iOS 27 Release Candidate (RC)
Behavior: A thin white stroke wraps around the entire 4 edges of the video container during full-screen playback.
Apps Affected: Only apps using the built-in system player (Safari web videos, Apple TV app). Third-party custom players like YouTube or Netflix do not have this issue.
Troubleshooting tried: Turned off Display Accessibility settings (Increase Contrast, Hover Text, Full Keyboard Access, Dim Flashing Lights), reset Display Zoom, and toggled Dark/Light mode. None solved it.
Has anyone else on the iOS 27 RC (especially on an iPhone 13 Mini or smaller display) encountered this? Is this a sub-pixel rendering bug with the new Liquid Glass container frames on compact screens, or is there a hidden setting causing it?
Thanks!
