It either shouldn't be doing this or needs an investigation.

The new Windows Terminal.

There's another issue on the tracker that's pretty much the same thing.
Environment
Steps to reproduce
Make sure acrylic is enabled for your profile. Resize with window to more than ~160-180 columns.
Type.
Expected behavior
The window is larger and imputing text acts the same.
Actual behavior
Input lag increases significantly. Before resizing the window, there is minimal input lag, barely or not noticeable. After resizing (or starting with a column count > ~160-180), it is easy to type faster than the characters will appear on screen. This happens for WSL Ubuntu 18.04, 18.10, 19.04, CMD and Powershell. I'm not sure if this is specific to using a 4k display with integrated graphics or if this is a Windows bug with acrylic.
