Terminal + PowerShell 7 + Vim = Trouble on Win 10

[alan-isaac]

Windows Terminal version

1.17.11461.0

Windows build number

10.0.19045.0

Other Software

Vim 9.0 in PowerShell 7

Steps to reproduce

Launch Windows Terminal from the Win 10 Start menu. My default terminal shell is PowerShell 7, which loads fine. (By default, I run as admin.) I experience no problems running PS commands here. However, inside this PS7 terminal shell enter vim C:\temp\temp.txt (a simple ASCII text file) and suddenly things go badly awry, even though the file seems to load normally into a Vim buffer.

Expected Behavior

Vim should behave normally, as it does within PowerShell 7 when not using Windows Terminal.

Actual Behavior

To give just one example, suppose the first thing I do after loading temp.txt into a Vim bugger (see: Steps to Reproduce) is to press v (to enter visual mode). The line the cursor is on disappears and seems to be deleted. As far as I can tell (?) however, something has happened to the screen drawing.

I do NOT have this problem when I launch PS 7 from the Start menu and then start Vim in exactly the same way. So adding Terminal into this mix produces the problem.

Oh oh oh now that I've slept on this, I bet this is #14512. Can you try Terminal Preview (v1.18), and set that as your Default Terminal, and try again/?

Apologies, I've been away. The problem remains in Windows Terminal Preview Version: 1.18.1462.0 + PowerShell 7 + Vim 9.
