Vuforia SDK Version: 6.0.117 Unity -
Description with steps to reproduce: After a clean install of my app on Android, the Vuforia background video feed runs at a noticeably lower frame rate. The apps overall frame rate is good (the main thread updates and renders at 30 - 60fps consistently) but the video feed looks more like 10fps. There is no output to indicate an error and the tracking does work but at the low frame rate.
If I suspend the app by opening another app and go back it resumes correctly and problem resolves itself. The issue also resolves itself if the app is run again after that initial install. You can get the issue to re-emerge by deleting the app's local data (not the app itself) and running it again. This is 100% reproducible.
I have not managed to get this to occur in your sample apps unfortunately.
Any advice, suggestions or tips would be greatly appreciated.

Hi, I have also meet this issue on my app developing.
I have doubt for Vuforia SDK version, so, I have installed older version like as Vuforia 5.0.
But the issue was same. In my opinion, Vuforia SDK has some internal issue in managing memory, or GPU.
