How can i confirm it? It's the newest version of Firefox on Android...

Go to about:firefox or about:buildconfig and provide the version numbers and/or build changeset listed there.

Source: Built from: http://hg.mozilla.org/releases/mozilla-esr10/rev/f10a1ef4d89c

At about:firefox : 10.0.5 (en-US) mobile

That is mozilla-est10; you're going to want to upgrade to mozilla-15; Firefox for Android on Google Play .

Updated it, same problem... I'll try to make a photo of it...

Fields 1,2 and 9 were rotated by 90 or 270 deg. Field 3,4 and 7 were rotated by 180 deg.

I can reproduce on latest m-c build. No idea what's causing it but I see assertions and warnings in the logcat that I've never seen before. Adding roc since he seems to have added the original "How did we snap, then?" assertion and can hopefully provide more context. 09-04 10:58:26.771 I/Gecko (15046): ###!!!

Requesting tracking Fennec for gaming related improvements.

The patch here probably fixes this: https://bugzilla.mozilla.org/show_bug.cgi?id=777194#c28

I pulled the try build from bug 777194 and that does in fact fix this bug. Marking as a dependency so that we re-test this once that lands.

Fixed by checkin for bug 777194.

This is how the game looks on latest Nightly. Is it related to this bug, or related to bug 777194? The block's background is still displayed as expected now. -- Firefox 18.0a1 (2012-09-20) Device: Galaxy Note OS: Android 4.0.4
