[Bug]: Saving window no responding when I try to save a figure

[SM6251]

Bug summary

When I try to save a figure plotted with matplotlib in iPython3 (Qt5Agg backend) I can not select other directory than the default one because the pop-up saving window is irresponsive, only save and cancel buttons work. This only happens when interative=True ( plt.ion() ) though. In a addition when I click on "save" I get the following warning:

Gtk-Message: 14:53:05.865: GtkDialog mapped without a transient parent. This is discouraged.

Code for reproduction

import matplotlib.pyplot as plt
plt.ion()
plt.plot((1,2,3,4,5))

Actual outcome

Gtk-Message: 14:53:05.865: GtkDialog mapped without a transient parent. This is discouraged.

Expected outcome

Not a frozen window

Which IPython version are you using? If it is indeed something from the 3 series (which is from ~2015), some of the automatic integrations may not be there.

If you use the

%matplotlib

magic does it work?

Also see https://matplotlib.org/stable/users/explain/interactive.html

I'm also a bit confused why gtk errors are coming out of the qt backend.

ipython3 --version

The magic command works, but shows this:

Those warnings are a bit odd, but are harmless.

I also just read more carefully the mpl version of see you are on 3.3 which we no longer support. Do you have similar issues with mpl 3.6?

If using the magic fixes the problem and you can not reproduce this issue on a newer version of Matplotlib I would like to close this issue with no further action.

I'll close for lack of response.
