Android 6.0 Marshmallow : Weird error with fragment animation

Question

One of my apps in the app store works perfectly fine with Android 5.0, but since today I have my device upgraded to 6.0 I get strange errors. I narrowed it down to the fragment

Answer 1

In my case, my app didn't crash but the transition between activities was buggy on >6.0. The reason was that one of the activities had the windowBackground property from its style set to @null. I commented it and it got fixed.
