mesh2d example panics on macOS

[ekalosak]

Summary

cargo run --example mesh2d compiles bevy successfully but panics upon run.

Environment

• Bevy 0.12.0
• cargo 1.74.0 (ecb9851af 2023-10-18)
• macOS 12.7

Adapter

AdapterInfo { name: "Intel Iris Pro Graphics", vendor: 0, device: 0, device_type: IntegratedGpu, driver: "", driver_info: "", backend: Metal }

Other examples tested

bevy

• cargo run --example 2d_gizmos works out-of-the-box.
• cargo run --example mesh2d_manual fails with the same "bevy_render/src/pipelined_rendering.rs" panic.
• 3d_gizmos, 3d_shapes, 3d_viewport_to_world also panic.

wgpu

• cargo run --bin wgpu-examples water works out-of-the-box.

Other things tried

• As recommended in the cheatbook, I ran rm -rf target Cargo.lock && cargo run --example 2d_mesh. It fails.

Panic

Here's the full console output from cargo run --example mesh2d:

Notice that the ERROR log asks for a report in gfx-rs. Please let me know if this is truly a gfx-rs issue and I'll move it there. I'm posting this here because the use of direct.rs leads me to believe that Bevy tried to load DirectX support rather than, what I assume is more appropriate for my macOS workstation, the Metal graphics lib. However, notice that the AdapterInfo indicates Bevy is targeting Metal.

So, with that working theory, I'm posting here. Please let me know if I can provide other diagnostic info. The full traceback is backtrace.log.

@cwfitzgerald this one sounds fun?

Workaround

Woot. Using 0.11.3 makes the mesh2d, orthographic, etc. examples work.

Note

I wonder if my antique workstation being stuck at 12.7 might be part of the issue. Apple's docs show macOS >= 10.11 and the Metal Performance Shaders are macOS >= 10.13, but - maybe?

• Someone in the Discord also hit this issue, but theirs was resolved by updating to 0.12.1. I tried from release-0.12.0 and release-0.12.1 and neither worked.

I'm also using macOS 12.7.1 and can reproduce this problem on bevy 0.12.1.

[mockersf]

it seems it only crashes on macOS with intel graphics

[ekalosak]

Still open bug as of bevy = "0.13.2"
Another related issue has a suggestion that an unsupported notice be added for Apple x86_64 Darwin systems running macOS < 13 and XCode < 15.

As this issue does not appear to have much momentum, perhaps it's best to add the disclaimer to the docs and leave it at "won't fix"?

Workaround 2

I have a remote desktop setup from macbook to EC2 t2.large ($0.1 / hr) that works pretty well (can use fast compile with DLL, forwards graphics (but not yet audio)) - please see http://ekalosak.github.io for the blog post.

@mockersf should this not be considered "wont fix" and closed as such?
