mne_browse_raw conflict

Hi,

I've been trying to visualize custom-written raw files using
mne_browse_raw, but the EEG recordings are not being displayed. However,
if I scroll trough the EEG channels, I am able to read the amplitudes at
each of the time stamps and get the following message in the command
shell:

'libplot: truncating a polyline that extends too far for X11'

Has anyone encountered this before? What could be causing the browser's
erratic behavior?

Thanks,

--Gabriel
