Ion-app and components are not resizing after orientation change

Hello,

i have a problem with my app. When the orientation is changed the ion-app and some components are not resized properly. This behavior is not every time the orientation is changed and not on every page. Also the app was fine on release (mabye the webkit has been updated). I hope someone can give me a hint.

if your are using ion grid or row set width: 100%;

Even with the width set to 100% its not recalculated. :frowning:
