Hello.
All of these problems are visible on iOS but are ok on Android.
(With background color set to transparent)
1st problem: ListView, specificaly the group section. I set the background color to transparent, but it is white on screen.
2nd problem with modal page: Transparent background is show in grey.
(All background color set to black and text in white)
3rd problem with ListView and group section: There is a white line between the group and the items.
And the last one: in Master/Detail, the sliding part has a vertical white line on the right border.
