Android 4.4 を実行するPosiflex マシンでアプリを実行しています。私のホームページは webview です (Chromium 30 を使用します)。時々アプリがフリーズし、logcat に次のエラーが表示される
DequeueBufferWrapper: Failed to de-queue buffer
Native window is invalid
上記のエラーの後、次のスタック トレースも表示されます。

私は単にこのデバイスを使用しているだけで、Surfaceまたはカスタム ビューがどのように実装されているかを制御できません。この問題の回避策はありますか。このようなエラーの後、アプリがフリーズします。
