I am running fusion in Unity mode. I'm running a Windows 7 32bit VM.
I'm using Yosemite on a late 2013 Macbook pro, and this was also happening in Mavericks.
When I go to Mission Control while running fusion every unity window shows the same screen i.e. if I have Word, Excel, Internet Explorer running in Unity, as well as the Mac calendar app running - If I am focused on Internet Explorer and I go to Mission Control then all of the unity windows use the same preview as Internet Explorer, but the Mac calendar app looks as it should with it's own preview.
Is this a common issue that I can fix? Or is this a bug that needs fixing? Or something else?
