I’m using Compose HTML, and I’ve got a web view that gets rendered offscreen. (It’s being rendered offscreen by a Unity plugin, and then the frame buffer is copied over.)

I’ve noticed that the Compose layout engine seems to ‘pause’ when Compose doesn’t think it’s visible, though. The animations don’t play, and toggling state flags doesn’t trigger a relayout. Why is this? Is there a setting I can toggle, to force Compose to update the composable view?

I was halfway through typing a comment and then it got removed along with your original message (when you deleted it?) 🥲

Cfw relies on window.requestAninatuonFrame to schedule the recomposition. It's called only when the window is visible.

I'll have a look if there's a way to workaround

Perhaps providing a custom MonotonicFrameClock can help

Oh, sorry! I realized I had some typos, so I deleted and reposted. I should have just edited, sorry. This is great, though – thanks! I didn’t realize renderComposable had the extra parameter. I’ll give it a shot and report back.
