After searching for a long time, I think I found the bug report about this issue. It's really either a libinput or xorg bug. Are you using a laptop with touchpad by any chance? Blacklisting the touchpad input seems to have fixed it for me, but it's still too soon to be sure. You should give it a try and report back. https://bugs.freedesktop.org/show_bug.cgi?id=26213#c22 Let me know if that works for you. And now I'm even more prompt to jump ship and install Wayland. Xorg is a pain in the ass.
