Hey there,
I'm on 3.6.18-beta.
Animation mode
'Offset' activated
Filtering by 'Rotate' and 'Translate'
I select some bones and all their keys in the Dopesheet.
I offset them by 7-10 frames to the right.
The result is a jerky movement at some key frames, as if the new curves were not well calculated.
Workaround I've found is filtering first by 'Rotate', make the offset, and then do the same filtering by 'Translate'. If you do it this way the motion is smooth.
Not 100% sure, but I don't think this was happening to me in previous versions.
Thank you.
