Windows: cannot load due to format not renderable with vulkan

[Quackdoc]

Windows 11
Primary GPU: rx580
Secondary GPU: Arc a380
WGPU_BACKEND = 'vulkan'

it does work fine with DX12 however multiple other apps preform better with vulkan so I only noticed it thanks to WGPU_BACKEND = 'vulkan' being in my path thought at the very least it is worth reporting

Thank you for creating the issue @Quackdoc , will look on it. I have heard about this issue before in the discord channel but better have it here for documentation as well.

@Quackdoc could you try again with latest main?

[raphamorim]

You can test with canary release btw https://github.com/raphamorim/rio/releases/tag/canary-ddf5fb17c9228b9bd4abacc98adcf94294784a04

[Quackdoc]

[raphamorim]

@Quackdoc could you test again using this canary build https://github.com/raphamorim/rio/releases/tag/canary-e3451943a0d938becd58545bb0f14a344e6185d0

(sorry about delay with the fix, has been hard to test this format since I don't have it enable in my vulkan device capabilitites)

[Quackdoc]

Seems to have fixed it, and it seems pretty stable, thanks a bunch for checking this out

Thank you @Quackdoc for checking it 🙏
