Working in Unity mode on an MBA with Core i7 and 4GB RAM on Lion 10.7.4. Happens with pretty much any app. Hard to say what triggers the condition, maybe modal dialog boxes, e.g., Save, etc.
Mouse starts moving really slowly, as if it got trapped in sand. Lags behind actual physical mouse movement. I see that the host CPU usage goes to almost 33% with nothing else running when the mouse issue starts.
Tried disabling mouse detection for gaming mode to no avail.
Anyone else experienced this? Any potential fixes?
