So far, so good. Works well with Fedora 20 (kernel 3.13.6-200). No issues with X11. Screen resolution (2560x1600) acted as expected using a retina display with no need to force it using Resolution Switcher. Also, no issues with Gnome 3 flashing black and blue, but I also have the following environment variables set: CLUTTER_VBLANK=glx CLUTTER_PAINT=disable-clipped-redraws:disable-culling CLUTTER_ENABLE_DIAGNOSTIC=True
Unfortunately no. When you try, Parallels gives you an error asking for you to disable visual effects. The associated kb item gives you instructions on how to start in KDE instead of Gnome (which doesn't make any sense to me, tbf). Guess it just doesn't like Gnome, but I don't like KDE, so...
