[Unity] UI Elements render too far apart on left and right eye

[Stev-eH]

Hello forum, I've tried finding posts regarding this topic but I did not find anything.

I'm new to developing with Wave SDK (v6.1.0) with the Vive XR Elite. When displaying UI Elements I have a bug where the elements render too far apart, which causes them to overlap out of place and have ghosting effects.

This problem seems to occur at random and either is there after deploying or is not, restarting the device doesn't seem to fix it.

My canvases are on Render Mode: World Space

I have tried comparing my canvas setup to Wave Sample Scenes, but there doesn't seem to be any differences.

My project currently consists of:
- Wave XRSDK + dependencies
- Wave Native
- Wave Essence
No additional imports were done with Essence

My render mode is Single Pass

I've set up the camera so that it displays passtrough, on my first development build I've simply set up canvas (Width: 1080, Height: 1080, Scale.xyz: 0.005) with a white background and sample text to display, bug didn't occur.
On the second dev build, I've added a simple TCP listener to my project, deployed, bug occured.
Reverted changes, deployed, bug is still occuring.

If I need to supply more information please let me know.

Thanks in advance!

Hi @Stev-eH,

Did you try Multi-Pass?

If the issue still exists, could you share your project to us for further investigation?

I tried Multi-Pass but it has the same result

I hope the issue is recreatable and you can shed some light on what I'm missing, thank you.

Hi @Stev-eH,

May I know the ROM version that is running on your XR Elite?

You can check it by going to Settings>General>About>System version.

It is on 1.0.999.702

Hi @Stev-eH,

I build your project into APK and run on my XR Elite running with 1.0.999.702, I didn't see the ghosting effect that you mentioned.

Are you able to share me your APK build?

Or is the ghosting effect only will occur when you're using Direct Preview?

I've since been able to figure out the source of the problem, it's rather silly.

There was never anything wrong with the build to begin with, but since I was looking at my computer screen trough the passtrough, my eyes didn't focus on the UI Element properly which caused it to appear double for me. When I tested it again looking somewhere else the problem didnt occur.

Sorry for the inconvenience, topic can be closed now.

 

I'm using builds on device, not Direct Preview

I've attached a build with the repository.
