This is a repro in conhost.exe.

https://github.com/microsoft/terminal/assets/99262845/ea482c85-aa0d-4034-986b-e607a90698fd

Also, I only encountered the issue on a laptop computer.

@zadjii-msft commented on GitHub (Jul 17, 2023):

Since this repros in conhost, I'd guess this is an upstream issue with git-cz itself. The way it's redrawing the whole TUI each frame seems... inoptimal. Though that's probably more an issue with whatever lib they're using to draw than anything else.

That being said - what they're outputting here also doesn't look terribly expensive to output. Maybe there's some specific sequence of clear & print they're using that's specifically causing a frame to flush with the screen blanked.

Though, very peculiar that it repros even in conhost directly, on 22621. That makes me think it's not the #14677 bug.

Interestingly enough, I can repro this slightly on 1.18, and not at all on conhost (from 10.0.25903.1000) nor gnome-terminal. I reckon this is probably somehow throughput bound. It shouldn't be for a menu as trivial as this, but might be.

I have installed git-cz on a remote Ubuntu system. When I access and use git-cz via SSH on my desktop computer, it works fine. However, when I access and use git-cz via my laptop computer, I encounter this issue. I have tested this on both two desktop computers and two laptops separately.

@zadjii-msft
Perhaps it has something to do with the rendering mechanism of the laptop computer! Nevertheless, thank you for patiently reading through my poor English and responding. Thank you.
