Scrolling breaks the rendering

[DanikVitek]

Hello there. I was experimenting by implementing a calculator app in a form of a REPL. The UI parts are:

• input field at the bottom of the terminal
• history as a scrollable list of input + result, each entry rendered as a vertical pair of Text widgets.
  The app is implemented using the vxfw module.

Here's the repo

If there are many entries in the history, and you scroll it up and down, the rendering of the list starts to break. Could you please check this out?

Zig version: 0.14.0
OS: Linux Mint 22.1 Cinnamon

I gave it a try, and it couldn't get broken rendering but it seemed to hang after I had added a bunch of entries

As you can see, the messages start to spread across multiple lines onto the empty cells

I should have probably mentioned that I'm using Linux (Mint)
