Renderer doesn't fully clear when using Cmder

Without any inputs, the terminals look identical.

After changing the RGB values, the Cmder terminal leaves the top line each time there is a new render.

Thanks! Maybe a bug from Cmder?

I actually get that on yakuake/konsole as well on Linux. After every input, I would clear the terminal before it rendered again. Something that I got used to doing with my older regular cout/cin terminal programs, so it just stuck with me.

I tried Yakuake and Konsole. Things are working as expected: https://user-images.githubusercontent.com/4759106/226143128-226baa49-eed8-4202-83c4-765bf5c34ba6.mp4

When it does it for me is typically I'll have a button (doesn't matter if I use the keyboard or a mouse) and that button calls a different program and it will render like the above, although only one extra time. I don't know if it's related in calling up a second program in a separate thread or something else.
