Description
在官网的例子中，我似乎发现了内存泄漏，每次平移或者缩放时，内存就会增加，特别是数据量较大的时候，浏览器会因为内存的增加而变得卡顿
下面是我打开官网的例子测试的情况，可以看到内存一直在增加且无法清除

Research direction
Start with the webgl-draw-line.html example linked in the issue and reproduce the memory increase while panning or zooming with a large dataset. Inspect the example's WebGL rendering path and use browser memory tools to identify retained resources; done means repeated navigation no longer causes unbounded memory growth.
