I am running Windows 7 in Fusion 3.0.2, and have noticed that every so often on a regular basis something will happen with Fusion causing all new windows, or menus, or popups from running the mouse over items will just be completely white in unity. Any windows that were open prior to this point will continue to look normal, but any new windows or applications I open will just be white. Sometimes prior to going all white I can see the contents of the new window for about 1 second. If I switch to Window or Full view, then the screen is completely black. And if I switch back to Unity, then all individual windows go back to being white. I can still click on places within the window (basically guess) to interact with the window, but I can't see what I'm clicking (for example. I can click the top right where the normal close window button is to close the window).
Attached is a screen shot of a few windows and how it looks.
I have found the only way to return Fusion back to normal is to restart the program. Thus meaning I have to suspend, quit, launch, and restart.
