User(s) can reproduce this bug

If an MFC application is running on Windows 7 (using Aero) with an 'Office 2007' style and DWM Composition is disabled (either directly or through compatibility issues, e.g. running an older app like Corel PaintShop Pro X) the MFC app is not re-drawn properly. It doesn't appear to happen with the other styles, such as 'Visual Studio 2005' style.

Details (expand)

Visual Studio 2010

Compatibility

You need to create two apps, one is an MFC app and another is a small Win32 project to switch DWM Composition off.

1. Create a new MFC App with the 'Visual Studio' project style and 'Office 2007 (Silver theme)'
2. Build and run the app
3. Create a new Win32 Project with the default settings
4. At the start of the _tWinMain add a new line:

DwmEnableComposition( DWM_EC_DISABLECOMPOSITION );

(you'll need to include dwmapi.h and link to dwmapi.lib).
5. Build and run the app

You should see that the first MFC app has a re-draw issue around where the Menu was, the menu appears shifted down and the previous region is not painted at all.

When you close the 2nd Win32 app and DWM Composition is re-enabled something odd happens with the title bar. Sometimes the title bar disappears and sometimes the window controls are painted in a Win95 fashion.

Windows 7 Ultimate, x86, Aero.

App refresh doesn't happen properly. The menu area has shifted down with the previous region not repainting. Only seems to happen with the Office 2007 style.

You can fix the problem by re-applying the style.

App should refresh with the Windows 7 Basic theme.

Does that mean it will be fixed in VS2010 SP1? If not would it be possible to post the fix?

Thanks,
Dave.
