My worst experience was with a manager who had no software development background. He had about 8 years of project and product management and was assigned to lead a team of 12 developers on a new initiative. Everything had to be implemented his way that he read on some blog/article even though the team would show why it doesn't apply to our use case.

Not surprisingly, people quickly started leaving one by one (including myself) and eventually his team was merged with another and he was let go. A micromanaging boss is bad, an incompetent micromanaging boss is a disaster.
