If you need to go higher than a 25 pixel blur radius, then you can turn off hardware rendering.

android:layerType="software"

or

With software rendering:

(The two images above were taken from a Xiaomi 2 phone running Android 5. Newer hardware and software might give different results.)

This quality hit is undesirable but I found it to be acceptable for most cases. And there really wasn't another option since in addition to the above crash I was getting a lot of other very strange bugs when using hardware acceleration.
