CARBO: Some line plots cause crash when viewed

[jackiryan]

On the CARBO system (2048x512 resolution, 165 fps) line plots choke LiveView and cause a CTD. This may be related to the instability in the QCustomPlot when plotting chaotic data at high refresh rates.

We (@eliggett ) had some crashes when flipping between the profile tabs and the frame tab.. it might be related to this, and we fixed it here (line 181):
