I have been looking in the forums for almost an hour and the only thing I saw was on old post mentioning the Nvidia 301.42 driver will fix that issue. But I just finished reverting my driver to that version and it still renders all the time!
I have the latest version of PD12 Ultimate and this is really making editing nearly impossible for me as I need to preview often!
This is what it looks like, along with the green lines that are made above the timeline.

Notice that it is doing it when it is only a single effect without any video...
