ChromelessWindow TitleBar Fill MainWindow

[NGUYEN THANH DAT]

Sorry, I forgot to ask the question. But it's difficult to edit the post. I think there are some bugs in post edit.

So, I add the question in this comment:

How can I totally hide the control by the TitleBar?

Hi,

I have a problem with ChromelessWindow that the TitleBar is not fully filled to the MainWindow. As the image below, we can see the image under the TitleBar. It is not totally hidden by the TitleBar.

I reproduced the issue as attached. You can use mouse wheel zoom into the image to see the problem clearly.

How can I totally hide the control by the TitleBar?

Thanks, and Best gregards!
