Cursor is jumping all over the place!

I've experienced some issues with the mouse cursor in the latest 1.14 version. Basically, my cursor sometimes jumps all over the place (in-game), disorienting me. This happens most of the time while moving in any direction, as I haven't yet experienced this while standing in one place. Because I use a laptop, I figured the source of the problem might be with my palm touching the trackpad while using the keyboard, so I disabled my trackpad, but the issue is still present. I've also used multiple different wireless mice, nothing changed.

Thanks for Your help in advance!
