Q: The scroll behavior isn't smooth after updating to macOS Sierra

After the update to macOS Sierra the scroll-behavior changed, does anyone have same experiences?

 

I still can scroll trough any webpage without problems. I mean scrolling with 2 fingers on the touch-pad or scroll with the magic mouse gesture.

 

BUT: When trying to scroll slowly through large lists of selections, the touch just responses on fast movements, not on slow changes.

 

Steps to reproduce:

 

Open an website like twitter and go the preferences. Go to the time-zone list, open it and scroll through it. Can you move the cursor line by line?

 

You also can move to http://www.doyouspain.com/mietwagen/ , select an country like spain an try to scroll SLOWLY through the list.

 

(I just found: the operating system list at the end of this page shows the same misbehavior)

 

I found this behaviors using "Parallels Desktop". I can't scroll through documents any more like before the update.

MacBook Pro, macOS Sierra (10.12)

    Ok, found out that this behavior happens in other apps, too:

     

    e.g. in Affinity, when selecting a font.

     

    I can scroll through the list and pick one value with one finger, but in the past I opened the list (dropdown) and kept my cursor in one row, scrolling with two fingers up and down until the right value was under the cursor.

     

    When i try it now, the list doesn't move or moves more than one line.

    Yeah , I also opened font book via spotlight to select one font clicked with one single finger , and to scroll down used two fingers , if I'll select all fonts using command + A or moving three fingers from bottom to up side I could select all fonts .

    To , deselect them I pressed option key and selected single font .

     

    Thanks !

    Exactly the same problem on macOS Sierra.

     

    To re-produce it, right on this page, click your own avatar below the header, then click Preferences. On the Your Preferences page, click the Time Zone dropdown list.

     

    Try to scroll the items in the dropdown list with two-finger gesture on the multi-touch trackpad. It's laggy, unresponsive, and when you scroll more, it suddenly jumps many lines.

     

    There are other serious scrolling issues on macOS Sierra:

    Tried a clean install of macOS - there is the same problem.

     

    in a clean install of Osx everything is working fine.

     

    reported the problem to apple, please do the same to accelerate the process of an update!

    Taking the long-list scenario to it's extreme reveals some interesting behaviour. I installed unicode version 9 in Font Book (a list containing 128,237 character entries). Interestingly, scrolling through this list is remarkably smooth at various speeds, accelerations, durations and magnifications provided that the scroll is continuous; i.e. click and drag on the scroll bar to your heart(U+2764)'s content and it's all smooth scrolling but take your finger off the trackpad and all your systems are belong to nope (U+1F494) to a degree seemingly proportional to how scroll-happy (U+1F4DC - U+263A)? you were beforehand. Trackbad!! Perhaps somebody could translate this to scroll-hacky and solve the problem. Until then I guess the take-home message is .... "what scrolls around, comes around" lol

    I'm curious what you are referring to with that.  Font Book is normally for fonts rather than lists.  Is there a url for the Unicode Version 9 that you downloaded?

    Thanks for that info!  So what you were scrolling through in Font Book was the View > Repertoire for that font, right?

    Yes. Ive found that the issue is momentarily resolved (for maybe 5 seconds) when i run 'fc-cache -vf /usr/<username>/Library/Fonts'. I checked the size of /usr/<username>/Library/Fonts/.fontconfig/ , which is emptied by the aforementioned command, and it grows to 1.6MB as the scrolling begins to lag. It holds steady at 1.6MB as the lagging worsens and remains there until fc-cache is run again. Is the font cache capacity set too low?
