Hi
While testing out our current app with the latest Vuforia 2.8.7 with the new Extended Tracking feature enabled we notice some strange results while calling the QCAR::Tool::projectPoint on devices with Retina screens.
This can be seen by writing out the bounderies of the target described here https://developer.vuforia.com/resources/dev-guide/screen-coordinates this starts to happen when tilting the device and getting the EXTENDED_TRACKED status. As the device is tilted further away from the original target and it disappears off-screen the coordinates returned from QCAR::Tool::projectPoint start to be incorrect and returning coordinates on-screen in strange distortion.
Note that this works perfectly on non retina devices(returns coordinates that are off-screen). Is this a bug or am I missing something here?

No, we ended up disabling the extended tracking for now, If you do find a solution then please share it.
