Windows not appearing

[kevinJ045]

No windows appear. i tried most examples. but nothing appears. i tried this code:

const { Window, Canvas } = require('skia-canvas')

let canvas = new Canvas(32, 32),
    colors = ['orange', 'yellow', 'green', 'skyblue', 'purple']

for (var c of colors){
  ctx = canvas.newPage(canvas.width * 2, canvas.height * 2)
  ctx.fillStyle = c
  ctx.fillRect(0,0, canvas.width, canvas.height)
  ctx.fillStyle = 'white'
  ctx.arc(canvas.width/2, canvas.height/2, 40, 0, 2 * Math.PI)
  ctx.fill()
}

let win = new Window({canvas, page:-2})
win.on('keydown', e => {
  if (e.key=='Left') win.page--
  if (e.key=='Right') win.page++
  console.log(`page ${win.page}/${canvas.pages.length}: ${canvas.width} × ${canvas.height}`)
})

It just logs this:

and quits, i am on nixos with wayland.

Version 2.0 made extensive changes to the Vulkan renderer used on Linux (including adding debugging info to canvas.engine when gpu initialization fails). Do you get a different message when running this code on Skia Canvas 2.0?
