Performance Issues when Editing in Vim

I love Fluent Terminal and have been using it for a while now. However, recently I've discovered quite a performance issue when editing files with Vim inside WSL 2. To be specific, when navigating through the code in Vim, the editor stutters and lags behind my keyboard input very noticeably.

To determine if it's a performance problem related to WSL 2 or just Fluent Terminal, I did a comparison test on the scenario with Windows Terminal and Fluent Terminal

On the left is Windows Terminal, and the right is Fluent Terminal

As seen in the GIF, when scrolling down the page on Windows Terminal, it quickly renders new text with little lag. On the right, Fluent Terminal takes significantly longer time to render changes on screen. The lag may not be obvious in the GIF, but it definitely feels sluggish when typing.

I don't think this issue is specific to using Vim in Fluent Terminal, as I've noticed minor slowdowns from time to time, usually when there is too much text on screen.

Could you guys look into it? I'm also happy to help, but I'll probably need a few pointers to get started. Thanks!
