The two Babylon.js demos on the WebGPU demo page (https://webkit.org/demos/webgpu/) don't render correctly for me–they seem to load (as in, the background color changes the I see the FPS meter update) but trying to interact with them just makes them flicker in a way that I can't capture in a screen recording. For reference, I'm using Safari Technology Preview Release 91 (Safari 13.1, WebKit 15609.1.3) on a MacBook Pro (Retina, 13-inch, Early 2015) running macOS Catalina 10.15 Beta (19A558d).
Hi Saagar, do the other WebGPU demos work without issue?
The rest of the demos seem to work fine–the triangle, cubes, and flock look pretty similar to their preview image do at least. It's just the two Babylon.js ones that are flickery.
FWIW, the demos now seem to work correctly after updating to Safari Technology Preview Release 92 (Safari 13.1, WebKit 15609.1.4).
