External Email - Use Caution Hello, I am running Python 3.7.6 and mnedev version 0.20.dev0 on a Windows 10 Pro. Every time I plot the stc, I get to visualise the plot and I can use the interactive time viewer functionality. However, after checking the plot and closing it, I cannot proceed running the other lines of code as everything is frozen and it appears that the software is still running that command. The only thing I can do is to terminate the iPython (version 7.11.1) session and start a new one. Here are the lines of code I use to plot stc. surfer\_kwargs = dict(hemi='split', subjects\_dir=subjects\_dir, views='lateral',initial\_time=0.1, time\_unit='s', size=(800, 400), smoothing\_steps=5, background='b') brain = stc.plot(\*\*surfer\_kwargs, time\_viewer=True) Any idea on what might be causing the issue?

External Email - Use Caution Can you try running it in IPython and seeing if `%gui qt` helps? If you hit Ctrl-C while it's stuck do you get any traceback? You can also try upgrading traits, traitsui, pyface, mayavi, and PySurfer to see if any of these helps. You can also try the new PyVista-based visualization and time viewer interface with something like: with mne.viz.use\_3d\_backend('pyvista'):     stc.plot(\*\*surfer\_kwargs, time\_viewer=True) This mode/backend is being actively developed but hopefully would be usable for you. You'll need to `pip install pyvista` or so to try it. Eric ---

External Email - Use Caution Hello, Did this issue got resolved or is there any workaround? I have once heard that this might be the bug with the GUI and that there is no known workaround... I also have the similar issue! Thank you in advance.

External Email - Use Caution One possible culprit is the iPython GUI backend. Try running the line %gui qt at the beginning of the iPython session or notebook, before you do any plotting. -- dan Daniel McCloy [https://dan.mccloy.info](https://dan.mccloy.info) Research Scientist Institute for Learning and Brain Sciences University of Washington ???
