i.MX6Q CTS test failed

Hi all,

I am working on a i.MX6Q based board. When I'm running CTS test case "android.view.cts.DisplayRefreshRateTest#testRefreshRate" on R13.4GA (Android 4.0.4), it worked but failed when it's on JB4.2.2_1.1.0.

I checked the logcat massage. It claimed that the display fps is 60. In fact, it's 52.

Is it possible that GPU's efficiency is lower on JB4.2.2_1.1.0. or if there's any other reason cause this problem.

I'd appreciate any advice to solve this problem. Thanks.
