I currently have this one:
Is it possible to remove black stroke and have only highlighted? Does it violate any Google guideline about material design

It is totally an android lollipop bug. It happens to the framework and AppCompat version of the EditText and will be fixed in a future release. See here: https://code.google.com/p/android/issues/detail?id=80180
