The example says:
Using AMD RADV POLARIS12 (Vulkan)
The test says:
thread 'water' panicked at 'Image data mismatch! Outlier count 464 over limit 460. Max difference 213', wgpu/examples/water/../../tests/common/image.rs:134:13
I checked the `water-difference.png` file, and it's just a few dots
here and there. The example seems to run fine.
Structure
For the simplest examples without using any helping code (see framework.rs here), check out:
hellofor printing adapter informationhello-trianglefor graphics and presentationhello-computefor pure computing
Notably, capture example shows rendering without a surface/window. It reads back the contents and saves them to a file.
All the examples use WGSL shaders unless specified otherwise.
All framework-based examples render to the window and are reftested against the screenshot in the directory.

Hacking
You can record an API trace any of the framework-based examples by starting them as:
mkdir -p trace && WGPU_TRACE=trace cargo run --features trace --example <example-name>
