MacBook on OS Catalina no longer scrolls smoothly inside open windows
Hello:
In the past few das my MacBook has lost the ability to scroll smoothly. Scrolling is now annoyingly jumpy, and it is impossible to easily read a long page that requires scrolling. The problem occurs in a variety of applications, ranging from Word to Safari, Chrome, Firefox and Opera.
What is going on? How can I fix this?
Thank you,
Peter
