When setting stage.fullScreenSourceRect, stage.displayState to StageDisplayState.FULL_SCREEN_INTERACTIVE; and renderMode to GPU, mouse position is read incorrectly. This is not only for mouseX and mouseY position, but also all the mouse interactions with Sprites, Buttons etc are not working correctly.
Anybody know a solution for this issue?
Here is the bug reported, but there is no response yet.
