I found a bug having to do with the green Start Render line in the waterfall charts.
I ran a few test on page A, without checking the “Create Video” checkbox.
Start Render line is drawn right after the CSS file has finished loading and this is as expected/correct.
Compare this to the waterfall charts for the other test runs, where I checked the “Create Video” checkbox.
The green Start Render line is drawn too early, at the Connect time for the HTML. This of course is wrong since the browser has not received any bytes…
Pat > can you fix this? Would be great!
