Go to https://www.fxhash.xyz/generative/slug/%22-rekka-%22
Click on run
After the initial circles are drawn, it takes forever for the demo to progress further. I tried, and gave up after 1 minute of no progress.
Chrome starts progressing further quite quickly.

I don't think we're mainly waiting on the ring buffer here.
We're waiting on the D2DBitmap::Map in the canvas worker thread to read back data for getImageData.
