Figma it looks like vector editing has broken. Can't select points or segments (when in isolation mode) if there are other objects on the canvas that overlap

Omar Rizwan Alexander Bandukwala 🦋 Navaneeth M Nambiar Here's a screen recording of a quick demo. (I'm running a debug build in an emulator here which is why it's in a macOS window.)

Finally got to ~zero input-to-display latency on macOS. It has taken us a _lot_ of work to get here! This is a slow-motion capture of a 120 Hz screen running a playbit program that draws a rectangle where the cursor is. The slight lag you're seeing is not from rendering latency but from "old" mouse position data (we receive it from macOS window server in a event queue.) Remember that the mouse cursor is drawn with dedicated hardware (dedicated GPU plane) so dragging a rectangle is the ultimate input-to-display latency test.

If you have a EDR/HDR display, try this little mesh gradient Playbit demo on desktop in Chrome (only works in chrome and safari dev preview since we use async wasm) Built with our new wide-gamut webgpu renderer, shipping in a few weeks

This week we did a three day "App Jam" at @Playbit_ . Lots of cool things were built, like a multiplayer math art app and a MIDI composer. My own project was a flow-based programming app for graphics. As if Quartz Composer was multiplayer. Pure C & WGSL, no libs, 1.5M wasm file.
