Host is running Linux 4.7.2 with QEMU 2.6.1.

The same with:
 4.19.0-4-amd64 #1 SMP Debian 4.19.28-2 (2019-03-15) x86_64 GNU/Linux
QEMU emulator version 3.1.0 (Debian 1:3.1+dfsg-7)
and 

Windows 4.0 sp6 workstation.

This guest worked in virtualbox without issues.

Still exists in  QEMU emulator version 5.0.0 (Debian 1:5.0-5)  running on Linux  5.6.0-1-amd64 #1 SMP Debian 5.6.7-1 (2020-04-29) x86_64 GNU/Linux


Another observation  (not sure if 100% relevant) 
When I leave "Generic PS/2 mouse" as an ONLY pointing device, I can observe erratic moving ("jumping") cursor in (at least) windows guests (NT4 sp 6 , XP, Win 8.1)

QEMU emulator version 5.0.0 (Debian 1:5.0-6)



This is an automated cleanup. This bug report has been moved to QEMU's
new bug tracker on gitlab.com and thus gets marked as 'expired' now.
