Vim leaves text in the terminal

[vivekananthrp]

Windows Terminal version (or Windows build number)

Windows Terminal 1.8.1521.0

Other Software

Windows 10 (Version 10.0.19042 Build 19042) with WSL2 Ubuntu 20.04.
Vim (8.1.2269)

Steps to reproduce

When I open text files using Vim (8.1.2269) inside WSL2 Ubuntu 20.04, it leaves behind chunks of text from the text file in the terminal.

Steps to reproduce the issue:

1. Open windows terminal and open a tab with Ubuntu 20.04
2. Open a text file with enough lines for scrolling
3. Use keys pg-up / pg-down / g (to reach top) / G (to reach bottom) / scroll through the file using trackpad
4. Close Vim (using :q)
5. Scroll up the terminal
6. Chunks of text from the file appears in the terminal

The above issue doesn't happen if I just use the up-arrow or the down-arrow for navigating through the file inside Vim.

Attaching a screen recording of the above-described issue.
