+-display sdl causes mice with relative movement to read garbage offsets
+Description of problem:
+`-device virtio-mouse` and `-device usb-mouse` (and probably other mice which send relative mouse movement data) are behaving incorrectly under linux guest and jitter a lot. In this specific case it only seems to happen with `-display sdl` as I could not reproduce this same issue with other of the following configurations: `-display gtk` and `-display spice-app` running with virt-viewer.
+This behavior is not present when running a Windows guest with the same configuration using `-display sdl`
+
+Another weird side note: this behavior is less apparent when running `evtest` on the exact mouse device having issues.

+Steps to reproduce:
+1. Install guest operating system
+2. Install gnome metapackage and enable GDM
+3. Reboot
+4. The mouse shows jittery motion on the GDM screen.
