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.
I dunno much else about the Android side of this, but I do know the Mali DDK is just one part of the variables there. You can't say everything is the same just by looking at DDK patchlevel.
You also need to check the Mali IP version number (like rXpY) and the DDK version the Mali kernel driver came from. There are some DDK build-time choices that are tied to which Mali IP rXpY you target the build to.
Unless they use the same kernel sources, git diff between the two mali directories in the kernel for the two platforms might give a hint.
I don't know if that's related to your issue but you do have to tie those down as well as the DDK (userland libs) to understand the differences in hardware and software environment between the two platforms.

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.
