Some Brain GUI widgets don't look good on Windows

[hoechenberger]

I believe this screenshot illustrates my main issues:

• The toolbar is filled with white nothingness
• The "reset" rescale button is smaller than the plus and minus buttons
• The plus and minus rescale buttons look weird, the symbols are not rendered in an expected way

This is on Windows 10 with MNE 1.1.

MWE:

# %%
import mne

mne.viz.set_3d_backend('pyvista')

sample_dir = mne.datasets.sample.data_path()
stc_fname = sample_dir / 'MEG' / 'sample' / 'sample_audvis-meg'  # omit suffix
fs_subject = 'sample'
fs_subjects_dir = sample_dir / 'subjects'

stc = mne.read_source_estimate(fname=stc_fname, subject=fs_subject)

brain = stc.plot(
    subject=fs_subject,
    subjects_dir=fs_subjects_dir,
    initial_time=0.1,
    views=('lateral', 'medial'),
    hemi='split',
    surface='inflated',
    size=(800, 500),
    background='white',
    time_viewer=True,
    show_traces=True,
    clim=dict(kind='value', lims=[3, 6, 9])
)

@alexrockhill just refactored the widgets after the 1.1 release, so there's a chance that this is already fixed on main. Can you check?

I need to use the new backend for the brain viewer, the backend is there but it's just not implemented anywhere. I think it should fix these kinds of issues.

I think there is no way we can realistically fix this for 1.2 in the next week @hoechenberger as the proposed fix is to swap in the new Qt backend for Brain which is a big undertaking. Bumping the milestone...

[hoechenberger]

@larsoner I actually just added it to the milestone to remind myself to check whether the problem actually still exists :) Which I'll probably do tomorrow!

Just to add to this, the help menu on macOS also covers some of the toolbar icons

[hoechenberger]

The menu should not be placed inside the window, but in the menu bar (which is detached and located at the top of the screen)
