intellij opens a "build output" window every time I type

Question

I edit my Java code, and pretty much every time I type a character, IntelliJ tries to build my app and pops up a ``build output` window. This window eats up half the screen and steals focus, making IntelliJ unusable.

This just started happening; I don't know what I changed. How do I stop this?

this is intellij 2024.3.2.2

The solutions in other similar questions suggesting project Preferences changes in Preferences --> Build, Execution, Deployment -> Compiler didn't help in my case.

I have an impression that the Build Output window started to popup after I accidentally clicked "Re-run automatically" on a Test configuration when running a particular JUnit test class:

I suspect that after that on every code change the test had to be run and for that the build had to be done and then its Build Output window poped up in case of any compiler errors (since without fixing them it is impossible to [auto] run the test).
