Hi,
I'm facing some errors in mne coreg gui.
1) There is no colour points displayed to set fiducials.
2) After loading functional MEG data as a Digitization source, it does not
display any thing, as per tutorial it should show sensor positions.
screenshot is attached
Thank you.
First you need to mark the fiducial points by clicking on the head, then
click "save" (or just click the "lock" button to exit "edit" mode).
If nothing shows up at this point, including the fiducial points, then you
have an OpenGL rendering bug of some sort. Feel free to open an MNE-Python
issue so we can debug your system config there.
