Comment 1 by torne@chromium.org, Jun 14 2017

Status: WontFix (was: Unconfirmed)
Are all the devices with this crash LeEco devices with the stack mentioning /system/app/webview/webview.apk ?

If so then we can't do anything about this - those particular devices are misconfigured by the manufacturer and do not use our WebView updates at all, so we can't fix any bugs. We've made the manufacturer aware of this and they may OTA the affected devices to fix their configuration, but I don't know if/when this will happen for any particular device.

This looks like a known GPU driver bug that we already worked around way back in WebView 49 by blacklisting some features on the affected driver versions, but since these LeEco devices don't get WebView updates, they also don't get the blacklist change.

Make sense, thank you.
