Corruption on Flash videos at www
User Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:32.0) Gecko/20100101 Firefox/32.0 (Beta/Release) Build ID: 20140607033236 Steps to reproduce: Play a video on www.weather.com. Example: http://www.weather.com/special/great-outdoors/video/is-this-heavens-gate-49424?collid=/video-minutes/great-outdoors Actual results: Black boxes appear when video starts. Once the video begins hovering the mouse pointer over the video causes it to flicker. Expected results: Video should play with no corruption.
Based on regression testing I've found that Bug 965967 is the probable cause. Turning off OMTC fixes the problem. Corruption doesn't happen on all Flash video sites. This bug might be graphic card/driver related.

Confirming, setting OMTC to 'false' prevents the black boxes jumping around during start of video. I've not experienced this on other videos, at least none I've watched so far. Win7 x64 here Tested on m-c build cset: https://hg.mozilla.org/mozilla-central/rev/62d33e3ba514 IE11 & Chrome play video normally without any small black boxes on start-up.
Status: UNCONFIRMED → NEW
Ever confirmed: true
Another video that also show corruption, though not as bad as on weather.com, is at cnn.com. Specifically, the video on the main page near the top left (Breaking News). Other videos appear to be OK.
I can confirm this issue on this page http://trojmiasto.tv/Stary-film-z-gdanskiego-osiedla-8477.html
