AugmentedImageDatabase reduce responsiveness of background camera renderer

dnnkeeper commented 5 years ago

SPECIFIC ISSUE ENCOUNTERED

VERSIONS USED

Unity: 2019.1.4f1
ARCore SDK for Unity: 1.9
Device manufacturer, model, and O/S: Galaxy S9, Note 8, Pocophone F1
ARCore: 1.9.190422066
Output of adb shell getprop ro.build.fingerprint: samsung/greatqltesq/greatqlte:8.0.0/R16NW/N950USQS4CRE1:user/release-keys

STEPS TO REPRODUCE THE ISSUE

Build HelloAR scene, notice how fast camera responses to the device movements and rotations
Add any Augmented Image Database to the session config (or build an Augmented Image scene) and build again
Notice how slowly camera reacts to motions. It lags for ~100ms or more

WORKAROUNDS (IF ANY)

ARCore SDK for Unity v1.8 doesn't introduce such lag

ADDITIONAL COMMENTS

I can confirm that. This makes tracking nearly impossible.

I'm using a Google Nexus 6P

Yes, same on my Pocophone F1 (snapdragon 845)

Confirmed over here too, on a Galaxy S8 after an image is added to the target database. The video background feed becomes juttery and lags a couple of frames then corrects itself. This happens indefinitely and makes image target tracking useless on ARCore in Unity.

I've also confirmed from one of my teammates that this happens on their Galaxy S7. We haven't tried downgrading our ARCore version number down to 1.8 yet as was suggested by @dnnkeeper. But yeah this is a serious bug!
