It looks to me the transparent (or alpla) hasn't been processed correctly. But can't

say at which level cause the problem.

Not sure if it is possible on hikey, but dumping the layers would help to see if is a

rendering problem or composition problem.

Hi,

I'm running into a problem on Android 5.1 when using keyboard to move
input focus among different application icons. It seems that the
problem may be related to how application icon is highlighted when it
gets input focus. On customer's system, the application icon will be
highlighted with a blur effect around it. As a comparison on hikey, I
found that the icons gets highlighted with a square block around them.
The attached pictures demonstrate the differences there.

I guess that such input focus highlighting effect should be done by
GPU. But the customer's system runs a same version Mali DDK as Hikey.
So I'm wondering if this different behavior is caused by Android level
of configuration. That's why I'm asking help from Android mail list.
Any comment or hint about how this different behavior comes will be
much appreciated. Thanks.

Regards,
Shawn
