Annoying animation when pasting long string into PowerShell

[kkshinkai]

Prerequisites

• I have written a descriptive issue title.
• I have searched all issues to ensure it has not already been reported.
• I have read the troubleshooting guide.
• I am sure this issue is with the extension itself and does not reproduce in a standalone PowerShell instance.
• I have verified that I am using the latest version of Visual Studio Code and the PowerShell extension.

Summary

I've had this problem since I started using PowerShell. When I try to paste a long string (usually a path) into PowerShell, it always plays a typewriter animation and I have to wait until it's done.

I am not confident that the problem is with this plugin, but PowerShell works fine after I disabling it, so I guess it's not a VSCode or terminal issue. The Terminal.app that comes with macOS is also fine.

Is there any way we could remove this animation? This is almost the only reason I don't use PowerShell.

Thanks so much for your issue @kkshinkai , it appears that this is actually a performance issue where the underlying calls to PSReadline delay the pasting in a way that makes it appear as an animation... I will mark this as a performance issue

[SydneyhSmith]

It would also be great if you could try our preview extension as some of the performance improvements released there may solve this issue

Hi,

I have the same issue on my Raspberry Pi 400 running Debian Bullseye ARM64. I also tried the preview extension, but sadly, pasting stuff is still as slow as the release extension.

I don't have this issue when pasting on Windows, perhaps it is MacOS specific? I believe the vscode terminal implementations use different VTYs between MacOS and Windows. Does this happen in a regular terminal too e.g. bash?
