Clientarea of Windows MFC SDI application frozen after returning from STRG-ALT-ENTF

I am using Visual Studio 2017 and I have created an MFC SDI Application with Direct2D for drawing. So I am listening to

ON_REGISTERED_MESSAGE(AFX_WM_DRAW2D, &CIGUIDEView::OnDraw2d)

messages for painting into the client area of the application. It all works fine, until I hit STRG-ALT-ENTF and return from the windows lock screen. Then the client area gets 'frozen', i.e. it is not refreshing. The application itself however is still responsive. When I set a breakpoint in

OnDraw2d(WPARAM wParam, LPARAM lParam){..}

Visual Studio breaks, so it is evident that all the drawing actually should happen. However, the application looks like this:

No graphics update in client area of MFC SDI application using Direct2D

Funny enough, this does ONLY happen when the mouse pointer is inside the client area while I hit STRG-ALT-ENTF. If it is outside, there is no problem.

Is this a bug or am I missing something?

Regards, Michael
