pixels: Applications exit/crash on window resize on Linux systems

Hi @parasyte,

I have written a small application using pixels and found out that the application crashes on a window resize. I can reproduce the same behaviour with running the example application minimal-winit.

Resizing the window provides the following error message: [2020-10-09T18:56:49Z ERROR minimal_winit] pixels.render() failed: The GPU failed to acquire a swapchain frame.

Removing the error handling on the pixels.render() call (line 49) and just unwrap()-ing it delivers the following error message: thread 'main' panicked at 'called 'Result::unwrap()' on an 'Err' value: Swapchain(Outdated)', examples/minimal-winit/src/main.rs:49:29

I tested the window resize on different Linux systems and graphics drivers: ArchLinux+amdgpu, ArchLinux+nvidia, Debian 10+intel. All systems were running X11, not Wayland. Performing a window resize with the example running under Windows 10 is working as expected.

I have also tested other examples from frameworks that base on winit (piston, amethyst) and window resizing works as expected.

Kind regards

Full Backtrace:
