I noticed this a few weeks ago, that after about 10-15 minutes I see an occasional horizontal jitter that lasts just for about half to 1 second, and then does not happen again until about another 30 or 60 seconds, sometimes more, sometimes less (no constant rhythm).
David, OP's above text precludes the presence of what you write with
"If so, there might be an intermittent HF spike sometimes on the sine wave from the generator." because the "shifted" situation lasts for a short while. In actual fact, I'd call it more a hopping than a jitter.
Ozan: The OP does not understand what you're looking for with triggering in Normal mode. I also described it: In Normal mode, with trigger level setting temporarily outside peak values because of level "jitter", no trace, so playing with the level, trace should be flashing irregularly because of level shift.
