QMimeData: wrong image pasted from clipboard

I have a strange issue on all my Windows platforms with Qt 6.2.1 and 6.2.2.
I get a wrong image if I paste a screenshot of a window obtained with ALT+PRINT SCREEN.

To replicate the issue:

• compile and start the attached project (untitle.zip).
• Press ALT+PRINT SCREEN and select a window (you can choose the application window)
• Click Menu Edit -> Paste

You should see the result of the attached image. The pasted image seems shifted.
With Qt 5.15.2 all works fine.

NOTE: pasting the screenshot on Microsoft Paint, then copy it into the clipboard and pasting on the Qt application solve the issue.
