Package: jupyter-notebook Version: 4.2.3-1 Severity: normal Dear Maintainer,
Thanks for this long awaited package. I noticed that when I plot an inline interactive plot with matplotlib (using the "%matplotlib notebook" magic command) a black square appears on all the cells, as in this screenshot: http://prntscr.com/dg36oy The black square stays there even if I open a menu (like the Edit menu), staying "over" the menu. I'm using Chromium, it seems that Firefox is less affected by this little but annoying problem. I can always reproduce the issue with this minimal code: ``` %matplotlib notebook import matplotlib.pyplot as plt import numpy as np t = np.arange(0.0, 2.0, 0.01) s = np.sin(2*np.pi*t) plt.plot(t, s) ``` When I start jupyter-notebook I get the following warning: /usr/lib/python3/dist-packages/ipywidgets/__init__.py:67: RuntimeWarning: To use the widgets with your installed Jupyter Notebook version, please install ipywidgets 4.x or earlier. version, please install ipywidgets 4.x or earlier.""", RuntimeWarning) but I don't think it's related. If you need further details or feedback just let me know.
