`Slab not found` error when running the `loading_screen` example.

Olle-Lukowski commented 3 weeks ago

Bevy version

current main

Relevant system information

I am on the latest stable version of macOS, latest stable rust too.

AdapterInfo { name: "Apple M3", vendor: 0, device: 0, device_type: IntegratedGpu, driver: "", driver_info: "", backend: Metal }

What you did

Run cargo r --example loading_screen, then, press 1, wait for load, press 2, wait for load, press 1 again, crash!

What went wrong

On the bevy website this seems to work properly, not sure if its a regression in main, or a macOS specific issue...

Full output:

Additional information

Decided to try it on 0.14.1, and there it works fine. So it seems like a regression, not sure if it is macOS specific, but for now I'll tag it as such.

Doesn't appear to be MacOS-specific? I tried replicating it on my machine, and got the crash too:
