SUMMARY

I do have 2 monitors and I'm using KDE Plasma 6.2.1 on Wayland. When I move my mouse pointer from one monitor to the next across the middle section, my mouse pointer is "glued" or somehow "stuck" at the border of each monitor. So the motion of the mouse pointer is not fluid but somehow awkward and a nuisance.

STEPS TO REPRODUCE
1. 2 Monitors
2. Move mouse from one monitor to the next across the middle section.
3. 

OBSERVED RESULT
Mouse pointer gets "stuck" in the middle.

EXPECTED RESULT
The mouse should move smoothly and fluid across the monitors.

Thank you for the bug report!

This is an intentional change, intended to help with accessibility and to make it easier to interact with UI elements that are near the border between screens, such as auto-tiling, interacting with scrollbars, side panels, and similar cases. This is documented in the Plasma 6.1 release notes (https://kde.org/announcements/plasma/6/6.1.0/).

You can reduce the strength of the effect in "System settings > Screen Edges > Edge barrier", or disable it entirely by setting the strength to zero. You may also be interested in the setting for "Corner barrier" in the same place.
