Description John Hardman 2015-07-06 13:41:28 UTC
When drawing a Button with rounded corners, on Windows (WinRT) the same color (the BackgroundColor of the Button) is shown outside the rounded corners as inside the rounded corners. This is not what I would expect, nor what happens on iOS. On iOS, the colour of the View behind the Button is shown outside the rounded corners. Displaying the BackgroundColor of a Button outside border of the Button on WinRT is not expected behaviour.

Hi Jason.

Is there any update on this? It's had a status of In Progress for 4 months. The problem still exists in XF 2.0

Many thanks,

John H.
