Description

I'm experiencing problems with spice-vdagent under Windows 8 and Windows Server 2012 R2 guests.

The guests are using VirtIO version 0.1.105. The spice-vdagent is version 0.7.3.

When spice-vdagent is running, mouse movement seems very sluggish. Very similar to a 1993-era serial mouse. If I stop the spice-vdagent service, mouse movement gets smooth again.

This situation also happens if: ... 1) The 'USB Tablet' device is added or removed; ... 2) The PS/2 mouse is added or removed; ... 3) The standard mouse (PS/2 mouse) is set-up as a 'USB Generic Mouse'.
