Two Puzzling Issues in Linux

[lalala-233]

System Information:

Operating System: Arch Linux
KDE Plasma Version: 6.0.3
KDE Frameworks Version: 6.0.0
Qt Version: 6.6.3
Kernel Version: 6.8.2-arch2-1 (64-bit)
Graphics Platform: X11
Processors: 8 × Intel® Xeon® CPU E3-1240L v5 @ 2.10GHz
Memory: 31.3 GiB of RAM
Graphics Processor: NVIDIA GeForce GT 730/PCIe/SSE2

Issue One:

The following Rust code snippets behave differently, which is quite perplexing:

let mut board = arboard::Clipboard::new().unwrap();
board.set_text("hello".to_owned()).unwrap();

versus

arboard::Clipboard::new().unwrap().set_text("hello".to_owned()).unwrap();

Issue Two:

It might be a KDE issue or something related to asynchronous operations:

let mut board = arboard::Clipboard::new().unwrap();
board.set_text("hello".to_owned()).unwrap();
panic!()

This code does not work as expected, but adding a sleep before the panic:

let mut board = arboard::Clipboard::new().unwrap();
board.set_text("hello".to_owned()).unwrap();
sleep(Duration::from_millis(100));
panic!()

makes it work. I suspect that it might take some time for the information to be copied to the clipboard.

Regarding the duration of the sleep, it generally needs to be more than 5 ms on my system, which I assume is related to system performance.

Otherwise, the clipboard remains unchanged, or I end up with an empty clipboard.

I've also meet the issue2, and maybe #143 and #114 are related to this
