Same sort of problem with this demo: http://www.fishgl.com/

FPS cut in half when OMTC is turned on.

[Tom Levels]

I think this can be closed since https://bugzilla.mozilla.org/show_bug.cgi?id=1000640 fixed the regression. Maybe, now another bug can filed for e10s (frame rate is about halved when e10s is enabled)?

Comment 8

[Virtual_ManPL [:Virtual] 🇵🇱 - (please needinfo? me - so I will see your comment/reply/question/etc.)]

It's still not fixed and e10s isn't enabled by default yet even on Nightly.

[Matt Woodrow (:mattwoodrow)]

This should have been fixed by bug 1000640.
