XF Android : I/Choreographer( 2699): Skipped 63 frames!

Hello,
I have a ListView, and have Image in each cell .

        <Image Source="{Binding Data.CompanyLogoUri}"
               WidthRequest="60" HeightRequest="60" Aspect="AspectFit"
             />

When my Networking is poor, it will show the following message:
I/Choreographer( 2699): Skipped 63 frames! The application may be doing too much work on its main thread.

Too many, it take the Visual Studio Android emulator very slowly....
When remove the Image from the cell, this issue not show again.

Environment :
Emulator : VS Android 5.11

Is it a bug ?
