WPF application window changes it's size

I have a WPF application for which the main window should be the same size all the time.

Therefore I set in the constructor:

Width = 1024;
Height = 768;    
ResizeMode = ResizeMode.NoResize;
WindowStyle = WindowStyle.None;
Top = screenBounds.Top;
Left = screenBounds.Left;
SizeToContent = SizeToContent.Manual;

screenBounds come from the Screen.PrimaryScreen in most cases.

I also subscribed to SystemEvents.DisplaySettingsChanged and redo the procedure above when the screen resolution changes.

In some rare cases this does not work and the application window is displayed in a different size (e.g. 768x556) but the screen resolution change event was not triggered. I have to mention that there is also a VNC host running on this system. So my questions: - What can cause a size change of a WPF window which is not detected by the screen resolution change event? - How can I force to keep the window the same position and size all the time?

My guess is something is manually setting the size in the code, but if you really want to prevent it from happening, I suggest you set:

this.MaxHeight = this.MinHeight = 768;  
this.MaxWidth =  this.MinWidth =  1024;

EDIT:

I found out that SystemEvents.DisplaySettingsChanged fires on a user changing the Display Settings. Try using SystemEvents.DisplaySettingsChanging which fires on any Display Setting change.
