nominating since this use case is common, and is a bad user experience

Some other change probably broke this. Diego, can you take a look please? 

Thanks

I cannot reproduce this from recent build

Gaia-Rev        a4c4cc86303a554facb8f45b7e764e5c4473c3de
Gecko-Rev       https://hg.mozilla.org/releases/mozilla-b2g37_v2_2/rev/8669c26fd4a5

Looks like similar button responsiveness issue is seen in other apps -- this bug https://bugzilla.mozilla.org/show_bug.cgi?id=1109527 seems related. However I tried both the camera preview hud buttons and the video menu buttons and not able to reproduce on 2.2 (flame kk engineer build).

No-Jun: is this still happening on 2.2?

Hmm, this was an intermittent issue, but on today's 2.2 and 3.0 build, I can't repro it anymore even trying for a while.  I'll close this issue and perhaps reopen it when it appears again.
