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:

2022-01-08T22:55:13.770261Z ERROR wgpu_hal::vulkan::instance: VALIDATION [VUID-VkSwapchainCreateInfoKHR-imageExtent-01274 (0x7cd0911d)]

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.

Yes please. One nit, but LGTM.

The first time (I think) that I've ever hoped that CI would fail.

Works for me on Windows 10, with an Nvidia GTX 1070 card. Sorry!

With the window size at 400x400 now, I think the example needs to be configured to run longer in CI

@DJMcNab

DJMcNab commented Jan 9, 2022

Wait why?

How would the example not running in CI allow it to work as a canary in CI for small window sizes breaking?

Edit: Sorry, misread the message.
It is 400x400, but it runs in steps of 4; therefore, it takes 100 frames in each phase, so 400 frames is a full cycle.

Suggested change
primary.set_resolution(width, (height - 4.).max(0.0))
primary.set_resolution(width, (height - 4.).max(1.0))

maybe this here and below works? May also need to be a couple of pixels bigger to account for window decorations.

It's worth noting that this hasn't actually caught the current minimisation regression - that's fixed in #4527.

To have detected that, we would have needed #4437.

Also @alice-i-cecile can you confirm whether you approve this now?

The minimizing example crashes for me on windows 10, but it also happens with other 2d examples, so CI should now be able to detect it.

Edit: I missed the discussion on where this should be. I agree that it should probably be in some kind of integration test and not an example.

@cart mentioned in #4370 (comment) that examples shouldn't be the place for this kind of tests

I agree with this. I'm going to block this on moving it into the tests folder and figuring out how to ensure that still runs in CI.

Looking good. I added some constants to make the example clearer and easier to adjust.

This is so cursed, but kind of makes sense? @mockersf I'll defer to your judgement here.

I don't get the point of doing that. Is it to make it easy to run manually?

It's because we currently have a scripting setup to run examples. And so if these are examples, they can be run by that setup.

LGTM if @mockersf agrees on the strategy of defining examples that live in the tests directory.

        Validation Error: [ VUID-VkSwapchainCreateInfoKHR-imageExtent-01274 ] Object 0: handle = 0x1adbd410a60, type = VK_OBJECT_TYPE_DEVICE; | MessageID = 0x7cd0911d | vkCreateSwapchainKHR() called with imageExtent = (225,56), which is outside the bounds returned by vkGetPhysicalDeviceSurfaceCapabilitiesKHR(): currentExtent = (225,52), minImageExtent = (225,52), maxImageExtent = (225,52). The Vulkan spec states: imageExtent must be between minImageExtent and maxImageExtent, inclusive, where minImageExtent and maxImageExtent are members of the VkSurfaceCapabilitiesKHR structure returned by vkGetPhysicalDeviceSurfaceCapabilitiesKHR for the surface (https://vulkan.lunarg.com/doc/view/1.2.198.1/windows/1.2-extensions/vkspec.html#VUID-VkSwapchainCreateInfoKHR-imageExtent-01274)
```
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

- We can't minimise if there's a 2d camera because ??? there legally must be a 2d target.
- Fixes bevyengine#4526
- Fixes bevyengine#4856

## Solution

- Make it not crash in those cases, just do nothing
- Seems to work ¯\\_(ツ)_/¯
- See also the companion commit in bevyengine#3597 - 503c247
