Default Mouse cursor jumps to other screen

I am running KDE with Ubuntu 20.04 on a Dell Latitude 5500 with two Dell U2412M monitors connected via a D6000 dock. For the most part, this setup works well.

The laptop screen is on the left and the two monitors are extended to the right.

In a Google Chrome browser on the middle screen, I was having some difficulty clicking in the scroll bar on the right side of the browser. When I tried to mouse into the scroll bar, the cursor jumped from the middle screen to the right edge of the right screen.

I replaced the connection for the right hand screen with an HDMI connection and the issue disappeared.

Unfortunately, I cannot upload the output from DLSupportTool, with NGINX reporting:

Default Similar Issue

I'm running Cinnamon with Ubuntu 18.04 on a Dell Precision 7530 with three Dell U2410 monitors - one (left, X screen 0) HDMI to the laptop, two (middle, right, PRIME displays) DisplayLink to the D6000 dock. The laptop screen is not used except during login.

NVIDIA Driver: 440.100, DisplayLink Driver: 5.3.1.34

I'm seeing the same issue and it makes using any UI controls very difficult when they are on the right side of the middle display, which is very frequent.

When the mouse is between 3-4 "mouse widths" from the right side of the middle display, its image (but not actual location) jumps back and forth to roughly the same position on the right display. Similarly, when very close to the left of the right display, its image jumps to roughly the same position on the middle display.
