We have a WPF application that's been around for several years. We've noticed that the window frame seems to have changed between .Net 4.0 and .Net 4.5. For example, for one particular <Window> (a ThreeDBorderWindow, whose XAML code has not changed for a long, long time), when we run the code on a .Net 4.0 system, it looks like this:
Now, when we run under .Net 4.5, it looks like this:
Notice that the window frame is "fat". The <Window> XAML element is fixed size, and so there's less room inside of it for the contents, which are clipped.
Is this change in behavior a known issue? I reiterate: the XAML code is the same for these, and I can find no code anywhere in our application (no styles, etc.) to explain it.
