pyplot show() opens functioning window only outside of rewalt, otherwise creates a non-responsive window about rewalt HOT 1 OPEN

Previously, I decided to switch backends to TkAgg, since
TkAgg, TkCairo, GTK3Agg, GTK3Cairo backends have been confirmed to work by @ahadziha.

However, despite having tk installed, it didn't work, so I found out that I could also install python3.10-tk.

Switching backends to TkAgg made it possible to display the image through Rewalt as well:

image = rewalt.drawing.MatBackend()
image.output()

Opens the pyplot window.

But that doesn't explain why matplotlib.pyplot produced the pyplot window on its own outside of Rewalt, simultaneously in the same session of the Python interpreter, when I used the GTK4Agg backend.

So I decided to switch back to the GTK4Agg backend and surprisingly, creating plots in Rewalt works without issues.

To reproduce the bug, I tried it with my WM on and off, just in case, without luck.

I've introduced logging in my branch and would like to close the issue only when I've successfully reproduced and fixed the bug.

Catching the bug if it's reproduced

1. Create a script that switches between matplotlib GUI backends, opening, closing, and drawing plots from Rewalt.
2. Use the pdb debugger on the script.
