I'm having a very strange issue where a copy of the cursor will appear on screen within 5 minutes or so of logging in. It stays in one place, above everything else (including the working cursor), until I log out or reboot.
It does NOT show up in any screenshot utilities or in SimpleScreenRecorder.
I'm running KDE desktop on Intel HD 4600 graphics.

I had a similar issue with the Intel HD 4600. The second cursor appeard sometimes when adding a second monitor with an usb adapter.
Turning the desktop effects off and on helped sometimes (shift + meta + E).
I think the problem disappeared after changing the acceleration method for the intel driver to sna. I also have TearFree option activated, fwiw.

Yep, I neglected to mention, but my second display is a Displaylink USB monitor. It's a weird issue, as I don't experience this on HD 3000, which my laptop has.
According to Xorg.0.log, I'm already running with sna. I've enabled Tear-free, we'll see what that does next reboot.
