Seeing the same problem with the expansion toggles in TreeView. 

Also on Windows 10, using Visual Studio.

Looking at the Gtk.CellRenderer Cell, the Foreground and background both have the alpha channel set to 0. Setting it to 1 does not fix the problem.

Same problem for me. On Windows 10, set Background Color to Cell doesn't solve the problem. it's really Text that desapear.

Hi, this being worked on?

I need to decide if I'm going to build a build alternative listview for my UWP app or postpone the release of my UWP app, until a fix is released.

As this is a very common way of building UWP apps I think the statement that Xamarin forms supports UWP should be removed.
