The problem is that Unity now attempts to automatically resize images to
power of two textures. The problem is that 432×163 is not a power of two. This
means that the image gets stretched (and thus mushy) so that even when it
is defined as the Config Dialog Banner ( Figure 18.10 ), it looks really bad in the
final build ( Figure 18.11 ).

Figure 18.10 Defining an image as the Config Dialog Banner. Figure 18.11 The poor output of Unity being a bit of a busybody.

The solution to this is simple but surprisingly poorly documented in the
Dialog Banner support documents. We just need to make sure that Unity does
not resize this particular image to a power of two image. To do this, select the
file in the Project panel, and then in the Inspector change the Texture Type to
Advanced. Change the nonpower-of-two drop-down menu to None and press
the Apply button to reimport the file ( Figure 18.12 ).

the banner image alone and leave it
at its nonpower-of-two settings.
