MediaElement导致合成器线程滞后 [英] MediaElement causing compositor thread lag

问题描述

当停止媒体元素中游（导航时）时，它最终会使合成器线程严重滞后。这在我的应用程序中大约有50％的时间发生。视频肯定会停止多次，但仍会出现延迟。滚动非常慢
和波涛汹涌，某些动画如加载动画很慢等等......有没有这方面的报道？这发生在使用media元素的多个控件中，它严重阻碍了我们的开发。

When stopping a mediaelement mid play (on navigation) it ends up lagging the compositor thread real bad. This happens about 50% of the time in my application. The video is definitely stopped, multiple times and the lag still occurs. Scrolling is very slow and choppy, certain animations like loading animations are slow, etc... Has there been any reports of this? This has happened in multiple controls that use the media element and it is severely hindering our development.
