What strategy was used for no visual glitches when resizing?

[axololly]

Again, I have to commend the effort that goes into something like this, with it being almost 20,000 lines of code and with no dependencies, but I was making a similar system with crossterm and I have to drop the poll rate to 1 or 2 ms. However, I simply just cannot get this editor to have visual glitches when resizing, so how do you do it? Do you subscribe to some kind of OS API event, or is it an ANSI code read on stdin?

In the meantime while this question is up, I'll dig through the source code in the hopes I can find what I'm looking for.

Thanks,
