Vuforia SDK Version: 7.0.36 -
Description with steps to reproduce: If you select .NET 4.6 in the player settings and build on Android, the first time you change scene, the video background becomes blurry and starts moving like crazy.
It doesn't comes back to normal until you restart the app. The adb logs show the following error when this occurs:
OPENGL NATIVE PLUG-IN ERROR: GL_INVALID_OPERATION: Operation illegal in current state
I tested on an iPad 5th gen and nothing similar happens.
Switching back to .NET 3.5 fixes it. -
Development OS (Mac OS X, Windows, Linux): Mac OS X -
Mobile OS and Version: Android Oreo -
Mobile Device Manufacturer and Model name: Google Pixel XL & OnePlus 3T -
Do the Vuforia Sample Applications show the same behavior?: Not tested
Same issue here. Blurry camera and moving like crazy. Even when restarting the apps. Target platform Android and building on Windows. Unity 2017.3.1f1. .NET version 3.5.
In my case, so far the issue only happening when i test it on Asus zenfone 2 phone (Android 5.0). No issue on other systems that we have yet. We have Samsung galaxy note 4, Lenovo tablet, Oppo phones (forgot the series) which all off them running on at least Android 5.1.
This issue never happened in Unity 2017.1.2 with Vuforia 6.
Update: Just done some test on Samsung Android 4.4 device. Apps runs smoothly.. So is it brand specific issue?
