GPU Crash dump
Skylake GPU hang while using GStreamer in a WebRTC call.
It means GStreamer is simultaneously encoding and decoding VP8 (in 1080p) using
VAAPI. The hang occurs very quickly (less than 5 minutes) when the bandwidth is
limited and packets are lost.
Issue seems similar to #110394 but this time related to VP8.
Also it is very easy to reproduce (few minutes only).
