Upgrading from 5.5.4 to 5.7 I noticed the play head is not jumping to the frame below the mouse in the timeline, left clicking does nothing. Scrubbing is also noticeable more stubborn, I have to jerk the mouse quickly in order for the play head to lock to the mouse.
The Level Sequencer works as fine though, clicking jumps the play head, scrubbing is responsive.
Is this a bug or some new changes to 5.7?
