A place for developers to talk about building on Farcaster.

/dev

Folks that are so surprised about all these React sites that re-render clearly haven't experienced anything other than React.

The problem is not the developer, the problem is that the React model makes it hard to avoid re-rendering everything.

This is the Android overdraw overlay on X (native) vs Bluesky (react native).

The React model is inefficient. Period.

The open web is dead, long live the open web. ⌐◨-◨

Can you ELI5 what "Android overdraw overlay" is and what I'm looking at with the colors?

Overdraw is when a pixel is rendered multiple times on the same frame. Red colors mean excessive overdraw.

This is usually caused when you have deep nested views that trigger redraws across.the layout hierarchy.

This doesn't map exactly to react re-renders due to state change. There can be many factors at play with such deep nested layout structures.
