I just tried updating my Geeksphone KEON to the 1.2 image found on downloads.geeksphone.com, and I found that a game I wrote (Helicopter) was running much slower, and had a weird ghosting effect.

In the attached image, the top screenshot is the game running on 1.1, and the bottom is it running in 1.2.

It is still present in the nightly build obtained from the same site.

I don't know much about how graphics code is shared between Firefox products, but it might be worth noting that this problem doesn't appear (nor have I previously seen it) in my desktop Firefox (OS X) - only on my FirefoxOS device.

Adding Nical who's working on graphics on the bug, hoping he can dispatch it or give it a look :)
