Thanks for the investigation. Yeah, the texmapper compositor is behaving correct also. The test is more specific to ca implementation, as I couldn't find a way to induce the needed behavior without implementation assumptions. From code perspective it'd be simpler if all compositors in webkit would share one behavior..

After replacing the WebGL backend with ANGLE we have a new bug because failures are different, this test is now flaky. The new bug is: https://bugs.webkit.org/show_bug.cgi?id=245840 The gardening commit is: https://commits.webkit.org/255008@main
