IntelliJ Idea, Gradle Junit Test - Output Shows Blank Lines

I am running Idea 2020.1.3 Ultimate.

I have created a Gradle project with Gradle 6.5.1 and Junit 5.6.2.

When running a simple test that only prints output to the screen, I see that after each line, Idea adds a blank line. This is making analyzing the results very difficult, since it doubles and triples the output.

This issue doesn't restore when running Gradle from command line.

It does restore when running with TestNG instead of JUnit.

It was also restored with JUnit 4 versions.

Any ideas?

Test code:

@Test
public void testDummy(){
  System.out.println("line1");
  System.out.println("line2");
  System.out.println("line3");
}

Output:

Testing started at 13:29 ...
