Unity: Textures disappear when camera gets too close in Oculus Quest

I have a Unity scene with a OVRPlayerController to walk around. When I approach a wall in my Oculus Quest (1) part of the textures on that wall disappear. Some clipping occurs. Obviously the stones should be visible on the entire wall. The same happens with the texture of the floor.



I tried to adjust camera clipping near. But that doesn't seem to be the problem.
Am I missing a setting? Like LOD or something? 
The wall and floor comes from a Blender scene.

Thanks!
