I'm also experiencing this problem, it seems to happen when you move the cursor directly over the progam.

The same issue on the amethyst issue tracker mentions downgrading to Rust 1.47.0 as a possible workaround for now.

this is the error i am getting with RUST_BACKTRACE=1
i am using PopOS 20.04
From the linked issue, it seems like this is down to rust 1.48.0 not working with winit 0.19.5. updating pistoncore-glutin_window to a recent version of glutin that uses a recent version of winit seemed a bit too involved for me as an outsider.
