I'm working on a project with module like MS Paint in 3D using Three.js and WebVR.
I'm trying to draw on texture using HTML canvas and plane mesh. I'm just using lines and arcs on a virtual canvas at the place of uvs given from raycast with plane intersection. Everything here works ok.
I've got simple example where you can draw by holding trigger when facing one of two planes.
When the user draws on the left hand canvas, it works normally and there are no bugs.
If you draw on the right hand canvas, and release the button weird bug apperas. You can see artefacts from the central objects and canvasses repeat 3-4 times on a row and follow you when you move your head.
The difference is the size of html canvas object but it affects whole scene rendering.
Bug only appears on Oculus GO. I have tested also Gear VR where browser seems to be similar to this on Oculus GO.
This bug have longer history. Previously it acted as alpha clipping mask which covered other objects so I have decided to attach just FYI:
