Safari Preview 143 on macOS 12.3.1 (21E258) on a macMini M1

I didn't see this "flashing" with prior combinations of Safari TP and macOS.

The test case loads a mostly blank page for me on STP 144, Chrome and Firefox. Is there something wrong with the test case?
Comment 3 Thomas Kumlehn 2022-04-29 12:49:54 PDT
The Page needs the HTMLModelElement feature activated.
Still loads on iPadOS15.5 beta 3 Safari. I only have access to TP143

The test case only provides a source of type USDZ, no other format

macOS 12.3.1 (21E258)
with STP 144
still shows the delayed execution of Scene start behaviour.
See black text panels flashing up on page reload in the uploaded screen recording.
