SurfaceGui clips into parts, causing z-fighting

Bug Reports Engine Bugs
1

This should be a Graphics bug. I started noticing this bug more recently, so let me provide details.

What’s happening?
Any instances displayed with SurfaceGui on the surface of a part does not render properly, partially clipping into the surface it is placed on and causing z-fighting between the SurfaceGui and the part.

What should be happening?
SurfaceGui instances should display normally on top of the surface of a part that it is placed on as it did before.

Steps to reproduce

  1. Place a SurfaceGui on a part.
  2. Place instances inside the SurfaceGui (Frame, TextLabel, ImageLabel).
  3. Move camera while looking towards the SurfaceGui. Z-fighting can be observed at certain angles and the part can be partially seen through the SurfaceGui as a result.

Device Information
I currently use a Windows 11 PC with an RTX 3060. However, I am not the only one who experiences this.

Attachments
Video (quality reduced, not taken by me):


Look for: SurfaceGui with ImageLabels and Frames placed on red neon part. Z-fighting can be observed.
Screenshots from video showing issue:

Z-fighting with textures elsewhere in video are Beams, not SurfaceGuis. Unsure if this is the same issue or if it is an issue with the beam placement. Ignore that for now.

I have observed this issue myself, but forgot to record my own video of it occurring. I will update this post when I see it again.

Extra Notes

  1. It is likely that this issue is only observed on moving parts, but I am not too certain about this yet. This is false. It occurs with anchored parts as well.
  2. It is likely that this issue is related to distortion caused by being located far from the game’s origin, but I am not too certain about this yet.

Any updates? The extra notes that I included may be helpful in finding the cause.

Still waiting for an update on this, if possible.

It doesn’t seem like this bug will be fixed…?

Will this bug be addressed? It’s pretty extreme.

it’s not a bug… your image is exactly at the surface of the part. You need to bring it out a bit, even by 0.1 will fix this issue. Place the image on an invisible duplicate part and it will solve this issue.

That’s… not how they work. A surface GUI on a part shows whatever is on the GUI on top of the part.

Are there any updates to this bug report?

Approaching one year of a reported, unaddressed bug. Fantastic.

Bumping this, this needs to be resolved. It obviously hasn’t been investigated.

Hi @Real_BenTheMiner is this issue still occuring? I tried reproducing with a simple SurfaceGui with a text and image label and unable to. However I’m on Mac and not Windows.

It’s possible that this issue has since been resolved. Let me know! Thanks.

Still happens!

Incorrect, the ImageLabel should not be clipping like that. Although placing an extra invisible part specifically for the image might mitigate the bug, it does not fix the issue itself

Glad to know Roblox is aware, I hope there’s a way this can be solved. I have seen this a lot on my M2 MacBook Air.

Thanks for confirming. Would it be possible to create a placefile that you could share with me that reproduces this issue? :folded_hands:

Yup, here you go:

I suspect the issue has to do with the distance to the origin.

I’m 90% sure both issues (GUI z-fighting and characters missing) have to do with floating-point error. the surfaceguis are WAAY too far from the center of the workspace (0, 0, 0)

and sadly it’s something roblox can’t just fix
here’s a video showing more about this issue:
