[roger21]

str :

go to twitch.tv
open a stream (preferably good quality, good network)
watch it in page mode -> no lag, no freeze of any sort
put it in full screen (from twitch video window button)


result :

get constant freezes of 3 to 10 second


expected result :

no freeze


i check my video drivers (and updated), flash options, firefox options, (i also blamed new twitch https policy but i can't change that) -> no change


got back to firefox 44.0.2 -> no freeze

Could you provide an example of Twitch stream which doesn't work in FS on your computer, please.
In addition, type about:support in the location bar and paste the section "graphics".

Does it work with a fresh profile?

the graphic section differs from the old and fresh profiles:

checking the differences in the configs, apparently it was "layers.offmainthreadcomposition.enabled: false" which once set to true (default) - plus a restart - first changed the values of the graphic section to those on the fresh profile and then made the freezes disappear in twitch full screen


still, my apparently **** profile was working fine with firefox 44.0.2 (and the freezes were freaking real with firefox 45, whatever the stream and/or the quality - just take the current most popular stream, providing it plays fluently in window mode, once in full screen the video freezes constantly: every 2-30 seconds the video freezes for about 2-15 seconds - while the audio continues to play, even the firefox full-screen-button-animation freezes along)

With a fresh profile, HWA and OMTC are enabled by default.
Anyway your Intel drivers are too old, you should find drivers from 2015 for Intel(R) HD Graphics 4000.

Jeff - can we remove the OMTC pref?

I've filed Bug 1259466

There are known issues with live streaming in Intel HD 4000 and old driver versions. You could try updating your graphics drivers.

Twitch.tv still uses Flash for live streaming, so moving this to plugins.
