How to make program output print instantly without a scroll animation?

In my code I print a status message to the console window every second. These messages appear instantly when the console log window at the bottom of the screen is not yet full. However, when the console has to scroll to fit the new message on screen, it does so with a sliding animation that makes it seem like all the text in the window slides upwards. This makes it difficult to keep track of which numbers in each print actually change. I would like the scrolling happen instantly to give the impression that there is no sliding motion, just numbers being updated.

Without success I have disabled Appearance -> Animate Windows and Appearance -> Smooth Scrolling in the settings menu. I have also tried disabling all system animations/sliding in Windows 10 Control Panel -> System -> Advanced -> Performance Options -> Visual Effects. Is there a way to change this behavior that I have missed?

A plugin that solves this would be fine, but I have been unable to find one.

I am running Windows 10 and IntelliJ IDEA 2017.3.5 Community Edition.

EDIT: As per request, a video demonstrating the effect: https://www.youtube.com/watch?v=RO-Qpe3rCf4. IntelliJ scrolling effect to the left, comparison powershell to the right. Try reading the text without pausing. It is almost impossible on the left, but quite easy on the right.

Creating this example, I also noticed that the scrolling effect did not seem to occur if only printing out very few (one or two) lines at a time.
