Hi Just bought MacBook Pro 2019 15 inch model with base config (2.6 GHz Intel Core i7, 16 GB 2400 MHz DDR4). There are certain apps, specially Apple News and iMessages (for messages where pics are being shared) does not feel fluid and I can see stutter while scrolling.
Is that usual, as I would not expect that from apps made by Apple? Just to add, it doesn't have anything heavy running at any time.

Sorry, I don't have Apple News or an OS later than 10.13.6 to test, but have seen some complaints & returns on newer Minis & Laptops, some with more than 1 return. :(
Safe Boot from the HD, (holding Shift key down at bootup), does the problem occur in Safe Mode?
System Preferences>Network, unlock the lock if need be, highlight the Interface you use to connect to Internet, click on the advanced button, click on the DNS tab, click on the little plus icon, then add these numbers...
8.8.8.8
8.8.4.4
System Preferences>Network, click on the little gear at the bottom next to the + & - icons, (unlock lock first if locked), choose Set Service Order.
The interface that connects to the Internet should be dragged to the top of the list.
Apply.
Open Activity Monitor & see what might be using CPU% the most.
WindowServer (10-14%), Kernel task 7.2 %, amazon music renderer 1.1 %. When I reside the apple news window, the lag is so obvious you can see Mac taking time to repaint the screen.
Other Apps like safari, amazon muic, pages, numbers they all work fine. Its only messages and Apple news.
Thanks for your reply. I am curious to know if there are other people who have same issues with MacBook 15 inch bought 2 months ago.
Hopefully you'll hear from them...
