Entering fullscreen mode will crash

[discosultan]

Entering fullscreen mode using ALT+ENTER will crash any sample. This is also an issue in the original C++ samples: d3dcoder/d3d12book#2

I tried just intercepting the Alt+Enter event in D3DApp::MsgProc. It's as though something else processes the Alt+Enter event, not letting me get my hands on it.

There's a bit of magic going on as Alt+Enter is something that the implementation of IDXGISwapChain handles internally.

Here are a couple of references for more information:

No longer seems to be a problem. Might have been related to drivers.

Still fails the same way for me. I tried Crate. And I'm right up to speed with my Nvidia drivers -- Geforce 381.89.

Not sure what's causing this - works without warnings for me.

I decided to change WindowForm to UserControl and then added UserControl to WindowForm.

Maximize the screen, then press ALT+ENTER. It defaults to trying to set the screen resolution to the window size - which does not always work.
