Ground Plane fails after multi-target on stereo setup

Vuforia SDK Version: 7.2.24 - Description with steps to reproduce: - Set Vuforia in "Phone + Viewer mode" (stereo), for instance with Viewer Type "VR Goggles (Merge)". - Set a plane using the Plane Finder (Interactive Hit Test for instance) - After setting the plane, look at a multi target object and track it (cuboid in this case) - After tracking it, take the cuboid out of the camera view - Then the plane won't work properly any more. Using Unity 2018.2.7f1 (64bit) and Vuforia 7.2.24. Here is how it looks using Vuforia in Fusion/ArCore mode (core-1.4.0): https://youtu.be/u4qA3BuvK48 And here is how it looks using Vuforia in standard mode, no arcore (same behavior): https://youtu.be/2oddaYL984Q - Development OS (Mac OS X, Windows, Linux): Windows - Mobile OS and Version: Android 9 - Mobile Device Manufacturer and Model name: Google Pixel 2 - Do the Vuforia Sample Applications show the same behavior?: Haven't tried it, but we are able to reproduce the issue very easily just using your scripts.
