I am using Unity 2019.2 with its Vuforia plugin. My initial scene is just a menu without camera, from which AR scenes are loaded- These use regular Image Targets for 3D stuff as well as UIs in different screen spaces based on needs.
With the current configuration, the AR works normally under all Android devices and on two iPhones, 7 and 11, with the latest software updates. Only on the only iPad I can test on, an iPad Air 2 with the latest software updates, there is a strange bug I can find no answer to:
As soon as I load into a an AR scene from my main menu, instead of showing the camera view, it shows the splash screen again, frozen halfway through the default Dolly animation, or sometimes a black screen or weird pixelated markings (like something was extremely zoomed in). UIs that use "Screen Space - Overlay", or "Screen Space - Camera" with a non-AR camera, work fine, and the Image Targets are recognised just fine. But my 3D stuff that should be laid over the image targets just doesn't appear (it's there and active though, scripts that rely on them work). So I can say with confidence everything in the app works and the Splash Screen is just hiding my AR camera view.
I have tried to turn the Splash Screen off via script in one of the AR scenes, but that simply didn't do anything. Adding an AR or regular camera to the start menu made the whole app crash/not start up properly.
In the ARCamera, I have tried to make the Background transparent (didn't change anything) and adjusted clipping planes (neither). Turning off the Splash Screen in the Player Settings just turned the views black. Changing the Architecture to ARM64 didn't change anything, either. The XCode log doesn't say anything useful, either - the camera is working, Vuforia is working, everything is working just fine, there is just a Splash Screen in front of the iPad's camera that shouldn't be there, by all accounts.

How do i properly use Overlay Canvas so that it is not visible over walls. As seen in the image below the canvas is seen through the wall(the white line in Game view). I am using a free roam camera that you can freely move in the Game. I tried using Screen Space - Camera canvas but when i move my camera in Game the edges are flikering.
What you are seeing in your game view is the "Gizmo", which shows the canvas outline. If you disable gizmos in the game view (top right of the game view, just click the "Gizmos" text", the white line will no longer be visible. This wouldn't show in a build of the game even if you have it enabled in your editor.
As Robin said, what you're seeing is just the canvas gizmo in the scene view. It's so big because it's scaled in world units to the resolution of your game view.
If it's getting in your way you can hide it without disabling it or turning off gizmos by clicking the little eye icon in the left of the hierarchy. The little finger icon will disable selecting it by clicking in the game world, so it doesn't get in the way of trying to select other objects.
If you're using an older version of unity, you may need to just disable the canvas and remember to turn it back on before you build, or disable gizmos.
I am building an application for Android-Oculus Quest. I set the canvas to Screenspace-Camera and it works perfectly fine in Player on Windows. That is, the texts are visible in the game view through Oculus Rift. But when I build it for Quest, the UI Texts disappear. They are nowhere to be seen. It is not just texts, even simple images are not to be seen. This is my set up. What is the mistake I am committing?
I had the same problem before. I guess your text is just too small. Try to scale your text and see what's happening
Just started in Unity I'm trying to make a platform game. But having issues with aligning the bottom of the platforms with the bottom of the phone screen. Everything looks fine on the Scene windows but is not right on the Game window or on the phone.
Figured it out, i guess. it was the camera, I reset it and noticed the camera view was off so i was able to move it to fix it.
When I start an app that the first scene contains too much data, after 3 seconds the Unity splash is like "frozen"... By this way, if I move my head to see any part of the VR world, all is black.
I can only see a rectangle area with the unity logo from the splash, but the remaining space is black.
I suppose that it occurs because all data of the scene are being loading, but, is there anyway to avoid this problem?
I'm using a Gear VR and a Samsung Galaxy S7 Edge.
Check this image to see that the user see if move their head after the splash is "frozen":
Thanks in advance.
Background
I am using Unity3D 5.3.5 to develop a Google VR (Cardboard) project
Introduction
I added a canvas button to my scene. It shows up in scene mode and sometimes in Game mode but never when I run the project
What I have tried
Turning off Direct Render for Main Camera
Setting up Render Mode of canvas to World Space
Adding Main Camera to Event Camera
Observations
Button shows up in Scene and Game Mode but not during Play mode
Though the UI does not show up, Physics Raycaster in the reticle hits the button.
Screenshots Below
This is a Unity bug. In the forums they mentioned it will be fixed in 5.3.5p5.
Its also noted in known issues for gvr:
Starting with 5.3.4p2, a bug in Unity prevents rendering World Space
uGUI Canvases into a RenderTexture
https://developers.google.com/vr/unity/release-notes#v080_initial_release
It works in older version(5.3.4f1), if you need to test it right now.
in your canvas change Render Mode to-> Screen Space Camera
change Render Camera to -> Your camera
change Plane Distance to a very low number but not negative
