I also have tried tighter and looser on the feed tension idler. I can't yet consistently tell if that is making much difference.
I have heard of others having this same problem. I think it was fixed (or at least mitigated) by easing up on the idler tension, and by increasing retraction distance so you're not running the same small bit of filament over the bolt, but a larger area.
