Streaming video lags while Audio continues normally when switching tabs

Posted

It only happens if I go from a streaming video tab to another tab or browser screen/software etc. anything that switches the main view of my screen from the video and back will cause this problem.

it will play fine at first, but once I look at facebook or bring up itunes etc, and switch back (usually doesnt occur right away, but once the video is a minute or two in it will 100%) the video will start to lag horribly and will never get back on track. the play buttons on youtube/netflix even stay as pause buttons even though I can click play and pause back and forth functionally, and the audio will never skip a beat, but the video will stop dead, lag a few frames and stop dead again and will never correct unless I refresh the page. I can't recreate this in chrome, I've cleared my history and caches, upped the storage size on the main cache and tried updating various things like flash and firefox (19.0) but nothing is solving it!

You can check for problems caused by recent Flash updates and try these:

  • disable hardware acceleration in the Flash plugin
  • disable protected mode in Flash 11.3 and later (?)
