Im getting wireframes tris visible on iOS devices for the background sphere (inverted normals) I setup in Blender. This issue is only in iOS and not in Android devices or Windows PCs. Anyone know why this happens and any workarounds to fix this?
Screenshot attached. Thanks in advance.

Hi,
Please provide the basic scene with just the background so we could check it on our devices.

Thanks for the response.
Attached the .blend file of the recreated issue.
Also found that the issue comes right after connecting the bump node.

Hi,
Thanks for sending this file. We checked the scene on several iPhones and it appears to be working just fine. What iPhone model you have?

I’m testing on an iPhone 16 Pro, in Safari browser.

It seems like the issue is only on iPhone 16 Pro.
Checked on a different iPhone 16 pro with Safari & Chrome browser, still the background showing its wireframe.
I checked the same scene on iPhone 13, iPhone 14 & 14 Pro, iPhone 15 and on an iPad 9th Gen & iPad Pro M1. All these devices rendered fine.

Does this device use the latest iOS version available?

Hi,
Yes, both the iPhone 16 Pro’s I checked are updated to the latest iOS.
(All devices I tested were upto date)

Hi Alexander, just following up on this. Since the rendering issue seems specific to iPhone 16 Pro across both Safari and Chrome (while all other devices tested render fine), I thought this might be useful for your team to check. Please let me know if you’d like me to run additional tests or provide a video capture.
Also, If anyone else here has access to an iPhone 16 Pro, could you try opening the test link above and let know if you see the same wireframe background? It would help confirm whether this issue is consistent across devices.

Hi,
Unfortunately, we currently don’t have this exactly iPhone model at hand to debug this issue. Perhaps there is something with how partial derivatives are calculated for A18 PRO GPU, which this iPhone model uses. We’ll let you know once would be able to reproduce this wireframe bug.

Thanks for the update. That makes sense — it’s definitely possible that the issue is tied particularly to the A18 Pro GPU. Appreciate you looking into it. Let me know if you’re able to reproduce this wireframe bug down the line or if there’s anything I can do to help with additional tests.
