Resizing the window creates a HUGE text mess

[PeterPedro]

Windows Terminal version

1.15.2874.0

Windows build number

19044.2251

Other Software

No response

Steps to reproduce

Write any command, the larger the better but make it easy to check if something gets disordered. Resize the window, try to do it multiple times if the first time you don't notice it, snapping to the corners might make it more obvious.

Expected Behavior

The text gets "reflowed" or ordered correctly depending on the window size.

Actual Behavior

A HUGE mess is created, the text gets duplicated and scrambled, the more times you change the window size the worse it gets.

Could you share maybe a screenshot/? What shell are you using, and/or what program is doing the outputting? I bet this is #3088 just based on the description, but I can't be sure.

I'm using the Windows Command Prompt shell but it also happens with Powershell and Ubuntu. It's not necessary to run anything, just type/paste some code or text.

I made a video, pasted your answer for an example. The behavior can be different sometimes because I don't have to scroll up always to see the issue, also sometimes the terminal crashes and I can't close it, only with the task manager.

This issue relates to multiple rendering issue and still no fix...

I'm working on a rewrite of the text buffer reflow algorithm but won't get to it for 1.18.

I am experiencing a similar issue with WSL terminals. The windows terminals (command prompt and PowerShell) seem fine.
