Roll oscillation when using right-angled docking ports

[cineboxandrew]

I've had a problem with controlling ships when controlling from docking ports at a right angle from the root part. Both SAS and mechjeb's Smart ASS have wild oscillations around the roll axis of the docking port, like its overshooting its attempt to stop rotation. This happens with both an inline docking port part like the shielded clamp-o-tron or with a normal docking port attached radially. I might try testing this in an unmodded install, but was wondering if anyone else has experienced this? I have several mods installed but the only one I can think that would effect SAS's ability to hold steady is mechjeb. Nothing out of ordinary appears in the logs

Edit: this is in 1.3.1 since I'm still waiting for mods to update
