bad behaviour of musixmatch application

[archz2]

My musixmatch app is not showing up properly in notification bar. The buttons come as blackened. However, they are functioning correctly. I am using Lollipop AOSP custom ROM on Lenovo A7000. See the screenshot.

I flashed the latest version of xposed framework after a fresh installation of AOSP Custom ROM. I have all my applications updated.
