Spinner graphical bug API 21

Question

I have one spinner in a fragment that have a very annoying graphical glitch. This occurs only on my Nexus 5 with API 21.

Answer 1

I managed to work around this bug in two different ways:

1. Set a style to your spinner:

maybe the background color in the predefined styles is enough for you. If not try

2. Create a shape drawable with a corner radius:

and set it as a popupBackground to your spinner

hope this is helpful!
