Examples crash when resizing on x11+vulkan (known commit)

[Azorlogh]

Description
Running the cube example, my window manager (on x11) hangs when resizing the window.
I have pinpointed the bug to the following commit: 1d0a22b

Repro steps

• Linux w/ X11
• Run the cube example
• Resize the window

Expected vs observed behavior
Expected: should resize and run smoothly
Observed: My WM hangs for ~5 seconds. Then it becomes responsive again, but the window has not been redrawn. Attempting to resize again at this point will not make the WM hang a second time, but the window never gets redrawn again.

Platform
Archlinux, X11, no compositor
WGPU version: Any commit since 1d0a22b
Adapter: NVIDIA GeForce RTX 2060 (Vulkan)

I am using 0.17.1 and i have the same problem. If i switch to plasma wayland session and launch my app and resize it, everything works fine.

But if i log in to plasma x11 session, then the app hangs the entire system for a few seconds if i resize it. After that, it just stops rendering and stays hanged (according to my logfile), and i had to use ctrl + C to stop the app smh.

There's a fix up, I'll try to land it tonight, sorry for the problem. To work around the issue, run cargo update -p wgpu-hal --precise 0.17.0 until I can patch it.
