Annotation Plot Error

I cannot reproduce this with MNE-Python 1.3.0 with the mne-qt-browser backend on macOS:

# %%
import mne

sample_dir = mne.datasets.sample.data_path()
sample_fname = sample_dir / 'MEG' / 'sample' / 'sample_audvis_raw.fif'

raw = mne.io.read_raw_fif(sample_fname, preload=True)
raw.crop(tmax=60)

with mne.viz.use_browser_backend('qt'):
    raw.plot(bgcolor='k', color='w')

produces a figure with black background an white traces.

Regarding the problem with the qt-browser backend when running from Spyder, maybe @marsipu has an idea?

Best wishes,
Richard
