wgpu example fails with "Swap-chain error: Outdated"

This happens on Windows 10. Changing the window sizes to 800,600 works though.

Thanks for filing this. I've seen something like that on some GPUs and not others, I suspect that it is related to resizing the window. I'll spend some time looking into how people handle that with wgpu some time soon-ish.

Could you try again with the latest changes of the master branch? I made a few changes which might have fixed this issue (it wasn't happening on my laptop so I couldn't test).

[phoekz]

I pulled a5744af7 and did cargo run --bin wgpu. I got the exact same error. And changing the resolution to 800 x 600 fixes it again 🤔.

Is it only printing the error in the terminal or also crashing the example?

[phoekz]

It prints the error once per frame, which is a lot of times when your monitor has high refresh rate. The window stays white.

OK goog to know thanks, I'll keep digging.

This is most likely a bug in Vulkan validation layers. See KhronosGroup/Vulkan-ValidationLayers#1340
