Feels bad on paper. Basically, this means zoom in/out is busted, right?

No, the app in focus wasn't receiving any input at all

Can you clarify what you mean by not receiving input? Touch input? Text input?

Touch input, in the case of filing this was a game app used and Gecko was basically ignoring all touch interactions to interact with the game at all. Console was flooding with:

That reads off as a P1 then - broken touch input, unusable game.

Although for me due to that other bug known right now, I can't even get apps to load at all right now.

Kats - Any thoughts?

Comment 7

[Mark Finkle (:mfinkle) (use needinfo?)]

Is this a regression?

Comment 8

[Brad Lassey [:blassey] (use needinfo?)]

Aaron to investigate whether this is a regression or not

I'm having trouble reproducing the problem. First of all the marketplace search didn't find those apps on my device; I had to grab the URLs from desktop FF. Starting PipesPuzzle with nightly in the background caused nightly to crash. Then, when I start pacman canvas after homescreening pipespuzzle, I got another nightly crash. [1]

After all that I closed down everything and started the apps again, and did get some of those error messages in logcat but only while in Pacman. If I switch to Pipes that game seems to work fine.

Looks like you and I can reproduce bug 844895

[Aaron Train [:aaronmt]]

I can still reproduce this on my Nexus 4 (Android 4.2.2); 

> iii) Load PipesPuzzle let it load, switch to home-screen, launch Pacman Canvas

Kats after you launch Pacman don't wait to let it complete loading

> iv) Switch to home-screen, re-launch PipesPuzzle, switch back to Pacman Canvas

After re-launching Pacman, the directional arrows to move the character do nothing. Again on every tap of one of the directional buttons I see in console:

E/GeckoPanZoomController(27226): Received impossible touch move while in WAITING_LISTENERS

I'm starting to think this is just poor coding in the Pacman Canvas app. Even if I just try to play Pacman canvas on its own none of the ghosts or pacman show up, and I can reproduce the "impossible touch move" log message by double-tapping (or generally doing multiple tap actions in quick succession) on the directional arrows. I can't get it to the point where the pipes puzzle app is broken, that always seems to work fine for me (modulo any startup crashes).

The Pacman Canvas app doesn't receive any input on latest Nightly 22.0a1 (2013-03-19) even if is loaded separately without installing other apps on my Samsung Galaxy SII (4.0.3).

At the time of filing the game did work fine and when I switched back it wasn't working. But I am not seeing this with other web applications at the moment. Closing as WFM unless Kats wants to address the E/GeckoPanZoomController(27226): Received impossible touch move while in WAITING_LISTENERS issue here.
