Unexpected rounded corners in Qt Frameless Widget
I use Qt and Windows API to create a window with a custom title bar, and I want this window to have some of the effects of a Windows window (maximize, minimize, close, etc.).
When I added the WS_CAPTION attribute to make my window have these effects, the title bar had rounded corners that were not what I expected.
I am developing on the Windows 10 platform and I am certain that this rounded corner is not related to Windows 11.
