React is the new PHP: a dangerously welcoming ecosystem for amateurs. If you look at the trace, you see it's firing a timer for LazyImage every 300 milliseconds that that's causing constant repaints. It's terrible, but no one believes in craftsmanship anymore. :-)
// Give react a chance to render before starting to poll
// This gives us more chance of the opacity transition being visible
// Should also fix rendering glitches in firefox where native image placeholder shows briefly
setTimeout(pollForComplete, 300);
},
Hmm, settimeout is one shot, setinterval is the repeating one, unless that’s calling itself recursively?
Anyway using delays hoping that things are in place in 300ms is asking for trouble, I thought reacts whole thing was to put everything in a component lifecycle callback so everything happens in the order it needs to
Hello! Thanks for having a fossick through our code ;) Happy to report that the issue has now been resolved. I've added a post explaining the underlying cause a little up in the thread. (I'm not sure how notifications work on HN, so figured I'd drop a reply here, too).
