To reproduce the regression, checkout this repo and run the examples

git clone --depth=1 https://github.com/ivanceras/titik

To run the examples using crossterm 0.18.0, the TUI is snappy and responsive.

cargo run --release --example simple
cargo run --release --example demo

To run the examples using crossterm 0.23.0, the TUI is very sluggish/slow.

cargo run --release --example simple --no-default-features --features crossterm_new
cargo run --release --example demo --no-default-features --features crossterm_new
