Sticky monitor edge is driving me nuts

Running Fedora KDE, I've got two monitors side by side. If I move the mouse slowly from one to the other, it seems to catch on the edge between. It makes interacting with things near the edges of the monitor a pain in the ass, if I overshoot with a large gesture to move the mouse to that region and then some unseen force prevents me from precisely moving the mouse back.

I can't find anything in the settings menu that sounds like it would turn this off. How do I turn this off? It needs to be turned off. I intensely hate it.
