Log Messages GpuProcessHostUIShim: The GPU process exited normally. Everything is okay. the stream contains missing packets in some of the IDR frame however in this particular stream they do eventually arrive (in most cases after 100ms). also in previous version of chrome the video would freeze on packet loss until there was a clean IDR frame to start decoding again. ideally i would expect the jitterbuffer to increase to better handle these late packets or freeze until a clean IDR came in

the video stops short of the problem. i dont see this in edge only because it freezes until it gets a clean IDR, chrome appears to play through it showing grey inp lace of missing slices in the IDR

Just tested it with 60.0.3112.78 (currently being rolled out) for ~5 minutes and I could not see any video corruption, I only get the freezes but I guess that is expected. stefan@mixer.com, could you please try the new version so we can verify that it has been fixed?
