With "not at other speeds" you mean not at faster speeds either?
Yes, of the four fastest speeds, 50ns/div is always jittery +/- 1/2 div.
20 ns is usually solid, with maybe 1/2 trace width jitter.
100ns/div and 200ns/div randomly can have excess jitter.

These show this symptom: OK (100ns/div) random (50ns/div) good (20ns/div)

A 7B70 does not do this, has maybe 1/2 trace width jitter up to fastest, (for it), 20 ns/div
7B10, 7B15, 7B92A do not do this either.
