This may have already been fixed; after updating and restarting I've been unable to reproduce, and padenot indicates he fixed a shutdown bug in MSG in the last week or so before I tested.. Also, further analysis by billm showed that only 10% of sessions had MSGStableStateRunnables, but in those 10% it was the most frequent runnable. This may be as-expected, since when in use the runnables are used to update MainThread media state 50-100 times per second. We hope to at some point move (most of) these runnables to atomics for updating MainThread, and we'll look to see if we can throttle the events/s from MediaStreamGraph. Note that monitoring entries in about:telemetry can be handy for tracking down issues. -- Randell Jesup, Mozilla Corp remove "news" for personal email _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
