[Video] Screenrecording of issue

When expanding the page beyond ~1600px, the background-image gradient changes colors:

data:text/html,<body%20style="background-image:%20linear-gradient(0deg,%20red,%20green,%20blue)">
data:text/html,<body%20style="background-image:%20radial-gradient(%20red,%20green,%20blue)">

Using test case from URL field and when I load it in 'MiniBrowser' based on WebKit ToT (267195@main), when changing width of window, Safari does have color shift compared to Chrome Canary 118, which does not.

This is a bug in a system component below WebKit.

This is being investigated as a WebKit bug again, re-opening.
