Buffer overrun in main_opaque_pass_3d in 0.16-rc.1

[alec-deason]

Bevy version

0.16-rc.1

[Optional] Relevant system information

Linux, both wayland and xwayland, intel GPU

AdapterInfo { name: "Intel(R) UHD Graphics 620 (KBL GT2)", vendor: 32902, device: 22807, device_type: IntegratedGpu, driver: "Intel open-source Mesa driver", driver_info: "Mesa 25.0.2-arch1.2", backend: Vulkan }

What you did

I updated to 0.16-rc.1

What went wrong

After updating to 0.16-rc.1I began to see this crash intermittently. I see it something like 1/4 of the times I run the program, the other times it runs without any panic. It appears to always happen in the frame where I first render 3d meshes. The splash screen and loading screens, which use only 2d and UI elements have never triggered the panic.

I have removed all my custom materials and pipelines and the error still occurs.

Additional information

I see other rendering glitches which may be related but I'm not sure. The other problem is that some, but not all, meshes flicker between being in the correct location and being offset or disappearing entirely when the camera moves. That feels to me like a problem with memory alignment or something in the bindings, which is why I think it might be related to the buffer overrun. But when I look at the frames in renderdoc it doesn't show any errors or warnings which I would expect if it really was related to alignment.

I'm still trimming my code down looking for a minimal example but I'm going to go ahead and post this now in the hopes that the problem is obvious to someone without that.

I just saw an example that makes me more suspicious that all the rendering issues I'm seeing are related to some sort of memory misalignment:

What you're seeing there is a circle mesh created with Circle::new and using a StandardMaterial. Like the other problems, this one seems non-deterministic. All instances of that mesh in this scene have the same distortion but if I destroy the mesh and recreate it the distortion goes away, or sometimes appears slightly differently like with just one vertex being out of place.

The faint dots in the background are unrelated.

[alec-deason]

While trying to understand the likely related issue in #18550 I discovered that removing all morph targets from my gltf models seemed to resolve that issue. The same appears to be true for the glitches in this issue as well. Without morph targets I have been able to run the full program several times with no glitches.

[alice-i-cecile]

Can you bisect this? Is this #17698 as well?

[alec-deason]

I'll see if I can. This project has a number of dependencies which make changing bevy versions tricky. But I'll see if I can get a less minimal version than what's in #18550 back to #17698
