我登陆页面使用了 vue-canvas-nest
登陆成功后前端路由跳转, 抛错如下

vue.esm.js?efeb:1741 TypeError: Cannot read property 'defaultView' of null
    at Sensor.destroy (Sensor.js?7005:83)
    at removeSensor (sensorPool.js?0732:63)
    at clear (index.js?272b:39)
    at CanvasNest.destroy (CanvasNest.js?dbdb:157)
    at VueComponent.beforeDestroy (VueCanvasNest.vue?29d0:31)
    at callHook (vue.esm.js?efeb:2921)
    at VueComponent.Vue.$destroy (vue.esm.js?efeb:2700)
    at destroy (vue.esm.js?efeb:4178)
    at invokeDestroyHook (vue.esm.js?efeb:5743)
    at invokeDestroyHook (vue.esm.js?efeb:5748)

强迫症看着很难受。

里面应该用了Window 对象，然后就是报错 未定义

vue 应该放到 peer dependencies 会比较合理一些！

线条抖动有点厉害，如果加个防抖参数能控制线条抖动就好了。

import vueCanvasNest from 'vue-canvas-nest' ;
components: { vueCanvasNest },
在data中定义了配置对象
data() {
return {
vueCanvasNestConfig: {
zIndex: 2
}
}
}
再调用时候传入进去

在页面中已经有了这个元素 但是我的配置对象并没有生效

if i add 'el', then occurs error:

TypeError: Failed to execute 'getComputedStyle' on 'Window': parameter 1 is not of type 'Element'

vueCanvasNest.vue:1 Uncaught (in promise)
TypeError: Cannot read properties of undefined (reading '_c')
at Proxy.o (vueCanvasNest.vue:1:66)

动态设置config为什么canvas还是未更新呢？

我在vue2.7.14项目中使用时，使用<vue-canvas-nest :config="config" style="position: fixed;width: 100%;height: 100%;"></vue-canvas-nest>，当页面在最上方时，焦点在鼠所指处，但是当向下滚动页面时，焦点将会在下方，而不是鼠标所指处
