Looks a bit like bug 1039818 -- probably the same underlying issue. FWIW, I can fix the problem by rotating my screen from portrait (broken) to landscape (fixed!) & back to portrait (fixed!). A reduced testcase would be really helpful, if someone can come up with one.

This is not a regression and I don't think this would impact a large number of end users so not nominating this to block.

WFM on a Flame running a nightly build from 2016-02-24. (The IE Fishtank code was last updated on 2014-09-18.) We may not be doing great performance-wise, though: 25 fps with 20 fish Comparison with a Samsung Galaxy SII (GT-I9100) running CyanogenMod 13.0 (Android 6.0.1): - Firefox Nightly: 14 fps - Stock Chrome 44: 57 fps

Closing as we are not working on Firefox OS anymore.
