Bug report

Bug summary

My problem is kind of the opposite to this stackoverflow question: Matplotlib plt.show() method does not pop out the window that my matplotlib always pop up ALL the previously opened windows together with the new window plt.show(block=False) opens. This gets annoying when I need to debug the code by generating some plots, Alt-Tab to switch back to code and generate some more plots. If only the last plot window is brought to the front, I need only 1 hit of Alt-Tab, now there will be a long list of tab-icons to go through before I get back to the code window.

I'm pretty sure it didn't behave like this before, probably after I reinstalled Anaconda and got a different version of matplotlib.

The backend it currently uses is qt5agg, changing to Tkagg solves the problem.
