12/26/2025, 9:06 PMthats very cool. I've been playing w\ a Flutter based desktop app, and it's resize performance is flawless, I'm very jealous

12/26/2025, 9:08 PMhuh Winit sounds interesting. Would love to see something other than AWT 😛 Plus something like Winit could open the door to... dare I say it? Native Compose multiplatform targets (Win/x86_64)?

12/26/2025, 9:40 PMya it's a really good question, because under the hood it's all, even Flutter, just using Skia

12/26/2025, 9:40 PMso I suppose it really does come down to the windowing API if that JWM example actually improves it
