You are right, this is different than before. But this is not really bug, but rather a change in behavior. Lock to Selection now also works in Masking, where it locks the view to the selected markers, but not with the completely broken behavior as in 2.91 and before, but rather in a way that actually works. Part of this change is that the view follows the active selection, but without centering the view. That way it is less jumpy and less distracting.

Roger that, but will be there a setting in preferences or in clip display to set the jumpy method back?
I've used to this type of behavior and in my opinion it's pretty handy, because instantly we have centered tracker/trackers.

@sebastian_k : if you think this is something that does not need any further ironing, please feel free to close.

To me though it seems a bit inconsitent though that we are "wanting" the jump when using the lock icon button (the offest gets zeroed, see rna_SpaceClipEditor_lock_selection_update) and in contrast dont want the jump when using the shortcut (see lock_selection_toggle)?

This is an intentional change which was done as a part of solution to jumpy view when performing various operations while Lock-to-Selection is enabled. I don't think it should be an option to restore old behavior, as the old behavior should be achievable by pressing . after L.

There is one annoyance still: the option from the tool bar will cause jump. Ideally behavior between this option and shortcut will be the same.But currently it is not very clear how this can be implemented.

I did document the change in the release notes: https://wiki.blender.org/wiki/Reference/Release_Notes/2.93/VFX#Motion_tracking
The behavior of toolbar will be consistent with shortcut shortly.
