Hello There..
I'm using parallels 10.0.2 on a MacAir 13, with LG 29 ultra wide external monitor. I use windows 7 on the VM in fullscreen mode on the external monitor. Since upgrading from Mac OS X Mavericks to Yosemite yesterday, every time I switch focus from an MAC APP directly to a windows app on the VM, the VM screen goes black.
I've made a video for better understanding. =>

[UPDATE]
problem solved after update 10.1
