Summary of the Pull Request

When Terminal is drawing in the non client area we no longer create 2 islands. Instead we create a single island and create a region that "pokes" the drag-able title bar area in the top right corner of the main window of terminal.

Capture

This change also fixes:

  • A crash at shutdown where the Application object is released early.
  • DestroyWindow is not getting called at shutdown for the all HWND (This have the effect of showing the window for a brief period after closing the app)
  • WindowsDesktopXamlSource.Close was not getting called at shutdown.

Is there a visual difference when changing this? Like does it remove the pixel gap between the islands or the frame? Or is it just the drag area?

Can you MSPaint on a screenshot what the difference is so we can visualize it more easily?

I'm comfortable with this. I just need a second signoff to merge it.

kinda odd how the borders at the top are rounded. Very few apps have rounded borders on Windows 10. One is Math Input Panel.

They already said this will change in the future, Windows is getting rounded borders everywhere

Introducing rounded corners after years of persistent sharp corners is hard and we don't have rounded corners right now anyway. I got a little off topic as it's more of a topic for the winui repo

The real technical reason this is happening is that we're suppressing window decorations and drawing over them, and the kernel component in charge of that (don't ask) gives us a region with rounded corners.
If we let the kernel do the painting, it looks like Windows Vista's Aero Basic.
Hence, the rounded corners.

* Use proper measurements for the draggable area
* Working better, paint works most of the time
* Fix a bug where paint is incomplete when double clicking the dragbar
* Remove old fork on XamlApplication
* Upgrade to XamlApp preview6.2
* Add Microsoft.VCRTForwarders to make it easy to dogfood
