Hi Team, Continuing this bug as separate website broken even with Safari Technology Preview 158 from Bug 240604. Comment - https://bugs.webkit.org/show_bug.cgi?id=240604#c8 Website Bug - https://www.by-us.studio/dc-open-19 It has splash like effect when opening in Safari Technology Preview 158 and before while Firefox Nightly 109 and Chrome Canary 110 open it much smoother. It could be animations bug rather than "Media" (object-fit) but I wanted to raise it to track better. Thanks!

Testing in parallel, same window sizes. Tested on macOS 13.3 --- Safari Technology Preview 159 18615.1.12.130.1 Firefox Nightly 109.0a1 10922.12.6 Google Chrome Canary 110.0.5462.2 5462.2 1. Starts with the 3 window with a pre-entered URL but not loaded for each browser https://www.by-us.studio/dc-open-21 2. Tap return in the URL bar for each browser consecutively as quickly as possible 1. Safari, 2. Firefox, 3. Chrome 3. Observe They are all loading stuff. The animation starts first in Chrome, Then Firefox. The water splash animates Then Firefox and Chrome are moving to the next slide… and Safari is just starting animating the water.
