Is this issue related to iced?

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

What happened?

When running cargo run --package integration I get a crash at startup due to a wgpu validation error:

Error in Queue::submit: Validation Error

Caused by:
    Buffer Id(4,1,mtl) is still mapped

What is the expected behavior?

The example should run

Version

master

Operating System

macOS

Do you have any log output?
