Created attachment 468576 [details] Broken behavior on Facebook Reels, TikTok, YouTube shorts Ever since I've upgraded to iOS17.1.1, I'm getting a broken behavior for `object-fit` in Safari on my iPhone: - `object-fit: contain` - the video starts either zoomed-in or out for a moment, then goes back to normal (sometimes it stays zoomed) - `object-fit: cover` - the video starts with a black flashing, then goes back to normal In the attached video, you can see the 2 behaviors on different apps: - Facebook Reels - `object-fit: contain` - the video starts zoomed-in, then goes back to normal - TikTok - `object-fit: contain` - the video starts zoomed-in/out, then goes back to normal - TikTok - `object-fit: cover` - TikTok tried fixing the bug, so instead of being zoomed, the video starts with a black flickering - YouTube shorts - `object-fit: cover` - the video starts with a black flickering

This should be fixed in iOS 17.4 beta. Please let us know if it's not, or if you are observing any other issues. *** This bug has been marked as a duplicate of bug 264293 ***

The issue seems to be resolved in Safari Technology preview(17.4). Is there any alternative fix we can apply until the safari release from our end?

The issue is also happening in MacOS safari. not just iOS in 17.3.1
