The whole AR scene jumps to the side 10-15 sek after placement

[llllkatjallll]

Describe the bug 💬

After placing a simple AR scene (via clicking on the white circle on the floor/table) the scene stays on the right position, but after 10-15 seconds it disappears and appears ca. 1-1.5 meter away from the previos position, on the right side.
I testet it on several Android phones with good light condition, it still happened every time.

Steps to reproduce 🔢

1) Create an object that should appear in AR and put it in AR Session root on position (0,0,0).
2) Export the project and open it with Android phone/tablet. ( or open my bugreport website https://bugreport-ar-placement.glitch.me/)
3) Start AR mode, place the scene in front of you. 
4) Wait for 5-20 sec, look at the AR object.
5) Expected: suddenly object disappears and appears on your right

thanks for the report. reproduced on android with the vite template

I see the same issue in three.js' AR example https://threejs.org/examples/webxr_ar_hittest.html
Can you confirm that @llllkatjallll ?

and I also had a few tests where modelviewer.dev did disappear and then re-appear
I also tested with Needle Engine versions going 3 months back and it consistently happened (using three 146) so it might perhaps be a chrome bug (i see the same behaviour in chrome canary as well)

Opened an issue in three to get more information mrdoob/three.js#26686

[marwie]

It's a chromium bug: https://bugs.chromium.org/p/chromium/issues/detail?id=1475680

Fixed in 3.19.1
