Follow-up Comment #5, bug #61208 (project octave):

You are probably referring to this hunk of the patch:

I was trying to be as clear as possible with the comment: It is "Exec" that
causes the flashing window for me. We did not call "Exec" before that patch.
So no flashing windows before that patch for me.
This patch adds a command that calls "wmic" using "Exec". That would cause the
flashing window (for me) unless the hunk above is also added.

Do who have suggestions how to make that comment more easily understandable?
