URL: https://github.com/apache/incubator-echarts/issues/9383
<!--
为了方便我们能够复现和修复 bug，请遵从下面的规范描述您的问题。
-->
### One-line summary [问题简述]
vue+echarts渲染的图表比较多，有时候会出现一个图表不显示的问题，再次操作全部图表都不显示了，会有个报错，尝试更改echarts版本没效--TypeError:null is not an object(evaluating 'this.ctx.dpr=this.dpr')
### Version & Environment [版本及环境]
+ ECharts version [ECharts 版本]:4.0.4，3.8.4，3.5.4都尝试过
+ Browser version [浏览器类型和版本]:ios手机safari，iphone 8P（12.1），7P（12.1），6P有问题；iphone 6s（10）没问题
+ OS Version [操作系统类型和版本]:ios12.1
### Expected behaviour [期望结果]
能够指导下怎么个情况，各种尝试都没能解决，资料也没有查到
### ECharts option [ECharts配置项]
<!-- Copy and paste your 'echarts option' here. -->
<!-- [下方贴你的option，注意不要删掉下方 ```javascript 和 尾部的 ``` 字样。最好是我们能够直接运行的 option。如何得到能运行的 option 参见上方的 guidelines for contributing] -->
