Having a problem where window contents do not display correctly. In the image below, you can see that a popup menu only displays the first few lines. If I run my mouse over the rest of the menu, it will repaint correctly. This happens not just with menus, but with dialog boxes as well (title bar with minimize and maximize buttons just appears white until I click on it). Running Windows 7 x64 (Coherence) in latest Parallels 8 on my Mountain Lion MacBook. Video settings are 256 MB with 3d turned off. I've tried turning off Crystal Mode, but it still happens. I also tried reinstalling the Parallels Tools/Drivers. I've been using Parallels for years and never had this problem until recently. Not sure what has changed.
