`RequestDeviceError { inner: Core(Device(Lost)) }` on macOS Monterey 12.7.6 since wgpu 25

[zhangkaizhao]

Description

RequestDeviceError { inner: Core(Device(Lost)) } on macOS Monterey 12.7.6 since wgpu 25

Repro steps

1. For the current wgpu 27.0.0:

cd examples/standalone/02_hello_window/
cargo run

crashed

2. For wgpu 25.0.2

cd examples/standalone/02_hello_window/
# set wgpu version to `25.0.2` in `Cargo.toml` and fix some version compatible issues in `src/main.rs`
vim Cargo.toml
vim src/main.rs
cargo run

crashed too

3. For wgpu 24.0.5

cd examples/standalone/02_hello_window/
# set wgpu version to `24.0.5` in `Cargo.toml` and fix some version compatible issues in `src/main.rs`
vim Cargo.toml
vim src/main.rs
cargo run

It works!

Expected vs observed behavior

• expected: show the hello window.
• observed behavior: crashed

Extra materials

Hum, this is an issue with indirect validation. This could be related to #8594 or #8616 or be a separate problem. Would you be able to try #8439 on your machine to see if this fixed the problem?

[zhangkaizhao]

Thanks for quick reply! I will try it when I have time.

Hello! I have tried #8439 on my machine but unfortunately this issue is still there.

The output of cargo run --bin wgpu-info is:

This should be fixed in #8674
