Bug Description

When the user resizes an app window the value returned by Screen.angleBetween(Screen.primaryOrientation, Screen.orientation) changes depending on the aspect ratio of the window. If the window has a landscape aspect ratio, one value is returned, otherwise another one is returned.

Screen orientation and app window size should be independent.

@Florian I wrote a simple test app (link below) and I am unable to reproduce this issue. Do you have any more information? I'm using a Nexus 7 with r379 and a bluetooth mouse. The output of the below app is always 0 regardless of window size.

@Josh: the issue is a little bit trickier it seems. I modified your program to show it: http://pastebin.ubuntu.com/15340361/

The value is only wrong for a very short period of time it seems. Somehow it returns to the expected value quickly after (without notifying of the change).
