Description
Applying transforms to a child and parent views leads to
flickering.
To be more explicit it looks like there is a lag between the
applied transforms.
I trying to apply a rotate transform to 2 views child-parent on the touchmove.
The initial testcase is this: http://pastie.org/1263792">http://pastie.org/1263792
After some talking on the forum I change it to set the 2d( also tried with 3d) matrix on touchstart and only modify it on touchmove. The effect is the same.
The attached screen capture shows the issue. The bike image should stay steady, but sometimes it moves with the parent view( the red one) then comes back in position.
Thank you.

Assigning to Ralf for triage.
We don't accept LH tickets opened by anyone except our trained Support staff.
The process is to submit a HelpDesk ticket and we will submit defects as appropriate.
What about all the recommendations in QA and webminars "if you have problems submit a bug to LH with a testcase" ?
Why don't you make LH private and so people won't "mess" with it...
Requires a complete & valid test case.
Ticket can be reopened if one is provided.There is a test case in the link.
Tested on the iOS simulator using TiSDK 2.2.0v20120821095711, issue still valid, flickering is still visible.
Closing ticket due to time passed and lack of progress for a number of years. Please open a new ticket if there are any problems.
