I have a file that has decided to scroll synchronously when I open it in a second window and start scrolling. scrollbind and diff are set to off. (:set scrollbind? prints noscrollbind and :set diff? prints nodiff.)What else can I try?I'm using neovim.
Turn off synchronous scrolling not caused by either scrollbind or diff
neovim;vimdiff;scrolling
As Christian Brabandt suggested in a comment, this can be caused by the 'cursorbind' setting.From :help 'cursorbind':When this option is set, as the cursor in the current  window moves other cursorbound windows (windows that also have  this option set) move their cursors to the corresponding line and  column.You can use :verbose set cursorbind? to find out what is switching this setting on.
