Go to https://codepen.io/mootytootyfrooty/pen/pvJRNBV
Measure the time for the lights to appear on screen.

firefox: https://share.firefox.dev/4f73M60 (38s)
Chrome: https://share.firefox.dev/3TOnmdm (8s)

Hm that's a large gap. The profile also looks a little different in FF. NI myself to take a closer look to see what's happening.

Can you still reproduce this? For me it takes about 15 seconds with Nightly on MacOS and maybe ~10 seconds with Chrome Canary. We're a bit slower but not 4-5x.

yes.

this is with all default options. The first profile had some non-default config options enabled (SA regalloc, self-hosted cache etc.)
