Stdout updates only on mouse movement

I have a peculiar problem.
I coded a lot of print statements to monitor participant performance online based on stdout.

The setup has dual monitors, one for the participant and one for the control of the experiment.
Everything works well except of the stdout, which updates only when I move the mouse (the participants only use keyboard). The code is a mix of normal print statements and some with modified separator and end characters (e.g. tab instead of new line).

Does anyone have any idea how I could fix it?

I found the same issue, have you found the reason, @mkoculak?
I tried with different versions (2020.1.3, 2021.2.2) but the same thing happens: I need to hover the cursor over stdout to see the print statement outputs.

Hi everyone,
I am having the same problem (version 2022.1.3)
Unfortunately I cannot hover on the runner with the mouse to see the print statements, as the mouse is used by the participant in the experimental window.
Is there any other more efficient solution?

Thank you!
