Elevation shadow does not vanish nicely for big MDCards

[j4ggr]

The larger the MDCard, the larger the shadow becomes, even if I don't change the elevation.
This means that it doesn't vanish nicely, but is cut off.

Here is a small example to reproduce it:

from kivy.lang import Builder
from kivymd.app import MDApp

KV = '''
MDScreen:
    theme_bg_color: "Custom"
    md_bg_color: self.theme_cls.backgroundColor

    MDBoxLayout:
        orientation: 'horizontal'
        padding: 20
        spacing: 20
        MDCard:
            style: 'elevated'
            size_hint: 0.1, 0.25
        MDCard:
            style: 'elevated'
            size_hint: 0.3, 0.5
        MDCard:
            style: 'elevated'
            size_hint: 0.6, 1

'''

class Example(MDApp):
    def build(self):
        return Builder.load_string(KV)

Example().run()

Then you will get something like the following screenshot (You can't see it well in the preview, please open the image):

• The shadow of the first and smallest card looks good
• The shadow of the middle card looks acceptable
• The shadow of the large card looks ugly

Here a little closer between the middle and the large:
