Glitches in displaying 3d model correctly with logarithmicDepthBuffer

Hello! I am using ar.js in combination with three.js (r136).
Im trying to load a custom 3d model from blender (model doesn’t have ngons, I tried both OBJ and GLTF loaders) but when I try to view it there were some flashy polygons. I thought that it was z-fighting so I enabled logarithmicDepthBuffer. After that there are no flashy polygons but model isn’t correctly displayed (Image — Postimages). I tried to view my model in web viewer like but there it is displayed correctly. Can some one help me?
I attatched all my files and made a public online demo (LoadingR) (3.4 MB)
P.S. For testing please use hiro marker
