- 当前 Bug 的表现（可附上截图） [图片] - 预期表现 次数占比 以及 错误内容展示正常。

[图片] 不知啥问题，开发工具正常访问，、正式版的分包页面点击进去后内容没有显示，，，官方是不是弄出啥问题了，求解释！！！！

在做一些长列表的时候，由于页面滚动过快渲染不及时导致页面出现空白，想请教下有没有方法控制页面的滚动速度，要是官方能开个API设置页面的滚动速度就好了 ^ v ^

[视频] 代码片段 不知道长列表组件是不是不支持一行两列的商品列表展示，recycle-view 在滚动过程中并没有发现滚动位置的变化，而列表内容却发现改变

[图片] [图片] 问题如图，，，，代码片段已给出，求路过大神、官方解答下是不是bug啊

[图片] 小米手机真机调试直接黑屏卡死，然后连体验版、正式版都进不了，官方来人解释下什么原因啊！

代码片段[图片] 我想用recycle-view做一个瀑布流长列表，在滚动过程中发现item的高度位置发生了变动，这是什么原因？？

bug 我在开发工具上看的，苹果X真机也会出现， 除非  duration  设为0 ，不然一直会出现 [图片]

有没有大神有啥比较好的解决方案或者思路没
