Is your issue REALLY a bug?

  • My issue is indeed a bug!
  • I am not crazy! I will not fill out this form just to ask a question or request a feature. Pinky promise.

Is there an existing issue for this?

  • I have searched the existing issues.

Is this issue related to iced?

  • My hardware is compatible and my graphics drivers are up-to-date.

What happened?

Iced straight up crashes when a vulkan adapter is found (so the fallback is not triggered), but it's incompatible (doesn't support some features).

related issues:

we were able to find a workaround for this issue:

What is the expected behavior?

The program should switch to the fallback renderer when wgpu crashes

Version
