Issue

EDIT:
I did type some stuff here but I managed to figure out what was causing it, so I'm editing.

It appears using Clear Buffer on Windows is causing huge whitespace gaps depending on the size of your previous buffer.

For example, you can see below with a small-sized buffer it only skips 1-2 lines;

But with a larger buffer, it causes much bigger whitespace gaps as shown below;

Hopefully this can be fixed.

Reproduce Clear Buffer on Windows 10 with both small and large terminal buffers, then trace the terminal buffer-clearing entry point. Done means clearing the buffer no longer creates whitespace gaps that grow with the previous buffer size.
