Crash sometimes on orientation

When having 3 or buttons in linear layout on orientation i am getting:
IllegalArgumentException("width and height must be > 0") when Bitmap#createBitmap is called.
Note that the in FlatShape#updateShadowBitmap when
val w = bounds.width() val h = bounds.height()
both width and height can be negative and this is not handled.
in the sample i run the height was -16.

Note that wrapping the linear layout with nested scroll view is a workaround to avoid crash.
