window::screenshot crashes when window is minimized

[rscarson]

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?

Calling window::screenshot while the target window is minimized causes a crash

thread 'main' panicked at C:\Users\rcarson1\.cargo\registry\src\index.crates.io-6f17d22bba15001f\wgpu-0.19.4\src\backend\wgpu_core.rs:3006:5:
wgpu error: Validation Error

Caused by:
    In Device::create_texture
      note: label = `iced_wgpu.offscreen.source_texture`
    Dimension X is zero

What is the expected behavior?

Either an empty image, or an error, or simply not submitting the result task are all fine

Version

crates.io release

Operating System

Windows

Do you have any log output?
