Q: Mouse scroll speed in Sierra

Since installing Sierra beta (5) and today the GM the scroll function of both the magic mouse and trackpad are accelerated to an unusable level on some apps.

 

I have noticed it with VLC (Adjusting the volume) and Minecraft (Scrolling through items).

 

I have adjusted it down to the lowest scrolling speed in the "Accessibility" section in System Preferences.

 

I don't really use other apps so it is unusual that it is causing issues with two unrelated applications. It doesn't seem to be an issue within the MacOS (i.e. scrolling in Safari is fine as is Chrome - but these are windows which might be different.)

 

Do other see this issue?

Is it a MacOS issue or something the developers of the apps need to resolve?

 

TIA

 

Glenn.

    I happen to know two types of software which scrolls lightning fast in macOS Sierra:

    • Java based application, e.g. PyCharm
    • The "classic" Terminal application

    And they scroll line-by-line, but not continuously like Safari or Pages.

     

    When I say "scrolls lightning fast", I mean when I swipe with two fingers from bottom to top of the trackpad of my MacBook Air, the Terminal application scrolls about six pages, or the PyCharm app scrolls 250~300 lines.

     

    That's insane.

     

    And here's what I tried, one by one:

     

    Rebooting to safe mode costs me 20+ minutes with FileVault turned on. DO NOT WASTE YOUR TIME!

     

    I upgraded my MacBook Air to Mac OS X Lion, then OS X Mountain Lion, then OS X Yosemite, then OS X Mavericks, then OS X El Capitan. None of them caused such an issue.

     

    Now we upgrade to macOS Sierra, and bad things happen, to a large group of people, to some specific applications. So this is DEFINITELY A SOFTWARE PROBLEM related to macOS Sierra.

    I think it is a problem related to JDK and Sierra. It has been reported here: https://bugs.openjdk.java.net/browse/JDK-8166591. I just don't know how long it will take for them to fix this. I just hope they can fix this soon because it is almost impossible to work like this.

    The problem also exists in safari or apps like affinity photo or designer:

     

    safari: try to klick on an popup selection with a long list. Before you could scroll through the lines line by line, staying with the cursor on the same place. Now slow movements doesn't move the cursor, faster movement move the selec row in a not controllable way.

     

    same in affinity when selecting a font. You can't scroll through the lists anymore.

     

    clean install of macOS doesn't help.

     

    can't do my daily work anymore. Please fix it soon!

    See this post, from a real expert: https://github.com/horosproject/horos/issues/125#issuecomment-246500472

     

     

     

    The problem is that multiple scroll events with offset != zero are being dispatched in Sierra. Very weird behavior. So, I didn't change the speed in the code, I did ignore some events.

    I have been noticing some issues in Safari too, but there the consequences are not drastic since you are not scrolling through images.

    In El Capitan, multiple events are dispatched, but they have offset equals to 0 until a relative area is covered by your finger(s) in mouse or trackpad.

    It's possible to implement speed control in Horos, but I will wait some time to confirm this is a new behavior in macOS - leading to refactoring of scroll function - or it's definitively a bug.

    Sadly, according to the record, Apple will NOT consider this a bug, but instead a new feature in macOS Sierra.

    If this isn't a bug I have to reinstall Capitan - never change a running system!

     

    I can't do my daily work with my productivity when I have to think about weird mouse-behavior.

     

    This bug is affecting me in

     

    • Safari
    • Affinity Foto
    • Affinity Desinger
    • Parallels Desktop
    • Teamviewer sessions
    • Remote-Desktop sessions

     

    I can't wait until all other developers have changed their coding to repair the bug of apple.

     

    Bug's in other applications like VNC are not nice, but they are not hamstring my work, my income!

     

    So - please APPLE: Fix the bug or give a sign that you won't fix it soon - so that I can take some time for a clean install of Captain.

    Same in here in each text editor or IDE, also terminal and VLC.

     

    As usual – Apple doesn't give a f**k and upset all users that care. I'm waiting for some 3rd party fix from Karabiner maybe.

    They would not be allowed to tell you, as they would have signed a Non-Disclosure Agreement (NDA) to get the Beta.  And asking them to break the NDA is not very polite.

     

    You can become a Beta tester if you need to know the answer, but you too would not be able to tell anyone else if it did or did not address the mouse scroll speed issues, as you would need to sign the NDA before you could get the beta.

    Thank you for this information. I didn't know that there is an NDA when signing in to the beta.

     

    I've just seen the announcement of the beta2 and am real interested in getting my problem fixed. I already thought about reinstalling Capitan, but this would take a lot of time. So it would be useful to get the information. To live 2 weeks with the bug would be uncomfortable, but if i would know, that this won't be fixed I would downgrade to do my daily work.

    I have a similar issue (the hyperspeed) but only when scrolling horizontally. I have it on all my Macs that I just upgraded to macOS Sierra. Especially annoying it is in Ableton Live where an accidental swipe to the left or right (while scrolling vertically) throws you left or right horizontally - it feels like a trackpad's horizontal sensitivity has been turned up to the max.

    I'm having the same bug.

     

    Programs it's affecting:

    -Adobe Photoshop

    -Adobe Illustrator
    -Adobe InDesign

    -Adobe After Effects

     

    It's totally unworkable.
