This view is not constrained. It only has designtime positions, so it will jump to (0,0) at runtime unless you add the constraints  The layout editor allows you to place widgets anywhere on the canvas, and it records the current position with designtime attributes (such as layout_editor_absoluteX). These attributes are not applied at runtime, so if you push your layout on a device, the widgets may appear in a different location than shown in the editor. To fix this, make sure a widget has both horizontal and vertical constraints by dragging from the edge connections.  Issue id: MissingConstraints
