Jittery tracking

[VF19_Wolf_Rider]

I think I might have found those energy saver bulbs in the Warm White range (2700�K) might be a tad red for TIR to work correctly.

I switched to a 3500�K (just a tad hotter colour temp than the ordinary incandescent light bulb) and tested, with the results being a much smoother tracking.

Cool White 4500�K, are a bit too blue for my normal use.

If it is showing up on the Tracking screen, it can cause an issue.
