Hi Mahesh,
Greetings from Syncfusion, we have analyzed the reported scenario and the mentioned issue occurs due to draw and clip related method changes done in framework in the latest android version. To know more about it refer the below link,
To draw the border for the TextInputLayout, when setting the container type as Outline, ClipRect and ClipOutRect methods are used, and they are handled based on SDK versions (For backward compatibility, we are in need of using both the methods). You can resolve this by setting Target Framework Version of the application to latest version (Android 8.1 or greater), but you can set the Target Android Version to any required version. To know more these settings, refer the below link,
Regards,
Michael
