I'm experiencing a jittery/buggy mouse cursor when moving my mouse over hyperlinks.
Every time the mouse transitions from the hyperlink pointer to the arrow pointer, the arrow pointer briefly visibly flashes in the wrong position before correcting itself.
This is in macOS 10.15 Catalina on my new 16" MacBook Pro, provided by work and with a variety of software installed. On other computers running 10.14 and 10.15 I am not experiencing the problem. I am connected to a 30" Apple Cinema Display via Mini DisplayPort to Thunderbolt 3.
- Hover mouse above a hyperlink. (Shows "Mickey Mouse glove" pointer.)
- Move mouse pointer off the hyperlink so that cursor changes to the arrow pointer.
- Arrow pointer initially flashes at the "top left" position of the mouse bounding box for 1 frame.
- Arrow pointer then flashes back to its true position, pointing at the same pixels that the hyperlink glove was originally pointing.
When I create a screen recording via QuickTime, the mouse glitch is not visible in the recording.
Here is an iPhone video of Mac's screen demonstrating this issue:

This is driving me nuts. On link-heavy pages, moving the mouse across the screen results in a dizzying blur of pointer motion. Middle-clicking a link also produces a similar jitter.
The problem remains after Restart.
