    Hello,
    I recently switched to a new macbook (Pro retina 15-inch mid 2015, OS 10.10.4) and am using Parallels 10.2.2. I used the migration tool to clone my old machine over which was working quite well (older slow machine but working). I am using a Windows 8.1 VM and extending the desktop with the thunderbolt display to a dual-link dvi converter to a dell 2560x1600 monitor. Coherence mode seems to be having some trouble now with the new machine. Non-coherence mode works and resolves, but coherence mode is black for windows and any program within windows. It seems to work natively on the laptop but not to the extended display. I'm hoping it's just some setting I have missed either in Parallels or Windows.

    @MikeB1 did you try to reinstall the Parallels Tools?
