# Objective
- Reduce confusion as the example opens a window and isn't truly "headless"
- Fixes https://github.com/bevyengine/bevy/issues/5260.
## Solution
- Rename the example and add to the docs that the window is expected.
# Objective
We keep getting issues where things break at small window sizes, e.g #3368 (caused by #3153), #3596 ('caused' by #3545)
## Solution
- Add a test that we can make small windows.
Currently, this fails on my machine with some quite scary vulkan errors:
```

```
etc.
This might be a new issue here, although I'm surprised it's vulkan giving this error; wgpu should stop it if this is illegal.
# Objective
- fixes#3344
- have example run faster
## Solution
- thanks to the nice folks at wgpu, I was able to switch from swift shader to lavapipe which is faster
- I also reduced the runtime for some of the examples
- I enabled the trace_chrome feature on the examples, and stored the results as an artefact. it can be useful to debug
- runtime is back to around 10 minutes

* Add a feature `bevy_debug` that will make Bevy read a debug config file to setup some debug systems
* Currently, only one that will exit after x frames
* Could add option to dump screen to image file once that's possible
* Add a job in CI workflow that will run a few examples using [`swiftshader`](https://github.com/google/swiftshader)
* This job takes around 13 minutes, so doesn't add to global CI duration
