1173863 - CSS Demo with lots of style recalc causes larger recordings to beachball

Status: RESOLVED INVALID

(DevTools :: Performance Tools (Profiler/Timeline), defect, P3)

Description

[Jeff Griffiths (:canuckistani) (:⚡︎)]

STR:

1. go to this codepen http://codepen.io/helenvholmes/pen/PqjEOw
2. open the profiler and the split console
3. run console.profile(); setTimeout(() => { console.profileEnd() }, 6000)

( possibly more than once, possibly with a larger timeout )

Expected: the profile should load

Actual: the browser beachballs, and for larger profiles can hang

This demo does a ton of style recalculation, it could be we're beachballing just because of the large number of style recalc entries.

This report is related to the old DevTools profiler implementation, which has been removed. The Performance panel is now based on Firefox Profiler at https://profiler.firefox.com/
Closing as invalid
