Applying transforms to a child and parent views leads to\r\nflickering.
\r\nTo be more explicit it looks like there is a lag between the\r\napplied transforms.

\r\n

I trying to apply a rotate transform to 2 views child-parent on\r\nthe touchmove.

\r\n

The initial testcase is this: http://pastie.org/1263792

\r\n

After some talking on the forum I change it to set the 2d( also\r\ntried with 3d) matrix on touchstart and only modify it on\r\ntouchmove. The effect is the same.

\r\n

The attached screen capture shows the issue. The bike image\r\nshould stay steady, but sometimes it moves with the parent view(\r\nthe red one) then comes back in position.

\r\n

Thank you.

What about all the recommendations in QA and webminars \"if you\nhave problems submit a bug to LH with a testcase\" ?
\nWhy don't you make LH private and so people won't \"mess\" with\nit...
