我正在使用 flutter_webview 显示带有一些 javascript 画布元素的 URL。

该 URL 在任何浏览器中都可以正常查看，但从 Android Studio 3.6 显示到 Pixel 3 (Android 10) 我在运行页面后大约 4/5 秒发生崩溃 - 带有以下控制台消息：

W/Adreno-GSL(10848): <gsl_ldd_control:549>: ioctl fd 61 code 0x400c0907 (IOCTL_KGSL_DEVICE_WAITTIMESTAMP_CTXTID) failed: errno 35 Resource deadlock would occur

我检查了开发控制台中的 Web URL，看看是否存在内存泄漏。通过浏览器显示时没有。

有谁知道可能是什么原因？

谢谢 CW

I met the same issue. You should check your WebGL code to make sure that you has to init the context before the WebView is visible to the user.
