Weird motion blur in applications on KDE Plasma

I’ve been experiencing this weird and nausea-inducing problem ever since I got KDE Plasma. It was easy to ignore for a while until it was very noticeable in games. There’s this weird motion blur, similar to a very mild but noticeable ghosting that has been happening in applications, including games like Garry’s Mod and BeamNG.Drive. It’s also noticeable when slowly scrolling text and makes things very hard to read when scrolling is needed, and when slowly moving the mouse, leaving a slight fading trail behind. I’ve tried to look this up for a solution but had nothing. I’ve tested this on a 1080p monitor and a 720p monitor, both LCDs at 60Hz.
