IE8 & IE9 Doc Complete Issue

[hlentz]

Hi,

i´ve encountered different timing values for doc complete when measuring websides with video and without video.

in the first measurement with video enabled the doc complete state is set allthough not all images are completly load.

the measurement without video sets doc complete at the right time, when all elements are loaded complete

the difference is visible in the waterfall and the Doc Complete Requests

IE9 shows the same behaviour
without video

with video

hope that somebody can help.

thanks & regards

From the looks of it you may have some code that is altering the page and that is timing sensitive. The video capture may be changing the timing just enough to get it to happen on the other side of the onload event. If you look at where the favicon loads that works as a good sanity check for where the browser thinks it fired onload.
