:cry: when I use pvr texture on iOS Platform ,and the mipmap level is 12 ,everything is correct

when I use pvr texture on Android Platform,and the mipmap level is 12,everything is correct

when I use ETC texture on Android Platform ,and the mipmap level is 1,everything is correct

But, when I use ETC texture on Android Platform ,and the mipmap level is (12), the texture is black,I don't know why,

Ogre/Samples/Character,this Sample Use Textures is in SampleBrowserNDK/assets/materials/scripts/Examples.material ,Open Examples.material you kan find Rockwall.tga ,then I replace it with TestETC3.ktx ,and put TestETC3.ktx in "SampleBrowserNDK/assets/materials/textures/" , then the floor is black, but when you
use TestETCNoMipMap.ktx, the floor is correct
OGRE: tag 1.9
Mobile Device: samsung note 10.1 2014 Mali T650

Do you know why, could you please help me ?

There is a bug in software mipmap generation which will be addressed soon.

Well, thx for your reply.
Can I have the bug id so that I can retrieve the issue.
BTW, could you give me the timeline that this bug will be fixed? Our mobile product will be released around the corner.
