[BUG] Scalp surface is not loaded for coreg GUI is fiducials exist (and looks bad/is unreadable in notebook) #10819
Description
When I rm /Users/alexrockhill/mne_data/MNE-sample-data/subjects/sample/bem/sample-fiducials.fif and then launch the coreg GUI with
import os.path as op
import mne
data_path = mne.datasets.sample.data_path()
subjects_dir = op.join(data_path, 'subjects')
gui = mne.gui.coregistration(subject='sample', subjects_dir=subjects_dir)
it works great. But if the fiducials exist before it's launched I get no scalp surface:
Also, you can't read anything. I know I can change my Jupyter Notebook zoom settings but I think this is an issue, it should look at least okay so that you can read things with the default settings on a pretty standard machine (below). I think the fontsizes should be way smaller so that the words don't get cut off.
