thought

• could the issue be that i am using intel-mesa? (Haswell Vulkan support is incomplete)

reproducer

• running the example:

nannou git:(master) RUST_BACKTRACE=full cargo run --release --example m_1_3_03

• throws:

Thanks for the issue @salkin-mada!

I have a very similar setup to you (running vulkan-intel on Linux) and I'm able to run the example:

However! I get a very similar issue to you as soon as I try to resize the window whatsoever. My guess is that your tiling manager attempts to resize the window immediately after creation however as the example doesn't account for resizing nicely it panics immediately.

@JoshuaBatty maybe it's worth going over these examples and check they can handle resizing? At least not panic!ing anyways. I'm down to help out 👍
