问题
I activated devtools experiments in
about:flags
but nothing shows up in settings.
Has something changed or is the feature gone? thanks
回答1:
Chrome DevTools used to have a canvas profiler, as Garbee mentions, but unfortunately it was removed. (There have also been other Chrome extensions for general canvas inspection, but AFAIK none of them are still working/maintained)
Firefox has a general canvas debugger that's quite good: https://hacks.mozilla.org/2014/03/introducing-the-canvas-debugger-in-firefox-developer-tools/
Safari also added a canvas inspector that you can turn on.
Also note: there may be an extension for your framework (e.g. the three.js inspector).

The experiment was removed. As far as I know it was never made stable, so that functionality is gone completely.
