Additional Information

This issue was introduced in 2.17.2326.103 by 2bb786c.

In Android N, DrawableContainer always invokes its children's mutate() method. If BufferedDrawable#mutate() returned its base Drawable, it'd be possible that that raw MozcPictureDrawable renders on h/w canvas directly.

Internal Issue ID: 25780510.
