Original GitHub issue: https://github.com/AppFlowy-IO/AppFlowy/issues/427

Describe the bug
Rendering -- highlighting tested -- is slow on monitors faster than 60hz.
Might be a case of being locked at 60hz

To Reproduce
Steps to reproduce the behavior:
Simply launch AppFlowy, and highlight on a page.

Expected behavior
Highlighting responsive, see the Screenshots section for a demonstration of both expected and current behavior

Screenshots
Here is a video that was slowed down (so it can be viewed on 60hz monitors) showing highlighting on a Chromium browser, and on AppFlowy

Desktop (please complete the following information):

OS: Arch Linux (64-bit)
Browser Chromium 99.0.4844.84
Version v0.0.3

The rendering issue is due to the old editor taking too much time to calculate the selection. We have optimized this in our new editor.
