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.
Should be fixed in 2.3.5-pre1. Thank you!

This issue still occurs , hence reopening the bug

I've just tested this again against the originally provided reproduction and 2.3.5-pre6 and it works as expected. Changing the accent color does not cause the cell text to disappear. I can only assume something is being cached incorrectly or something to that effect. Please try completely wiping your bin/obj/package folders, deleting the app, and that the same package version is being used across the solution.
Verified on xamarin.form version 18.104.22.1686-pre6.
ScreenCast link : https://www.screencast.com/t/LZEOqPvxMwIg
it seems that with the pre6 version the ListViewSelectedItemBehavior command now fires twice in a row when you click on a listview item. This makes our app crash due to unexpected behavior.
Can this be fixed?
That sounds like a different issue. Please file a new bug report with a simple test project that demonstrates the issue and please provide steps to reproduce the issue.
