Thank you for correcting the bug status and also thank you for the test
program. I have been trying to think of a simple way to show this issue, thus
far I have come up with the following.

I have uploaded two screen images, the one generated by SIV which is all offset
by one pixel relative to the Wine Screenshot. The actual code that SIV uses to
copy the window to the clipboard is below.

As it's only off-by-one pixel it's quite hard to see, but the SIV-Copy image is
all offset to the right by one pixel.

I released SIV 4.18 today which can be used to reproduce the screen images.

Is this enough to progress the issue?

The SIV-Copy image is also missing the border which I expect is a side effect
of using the Linux window manager. I am wondering if there is a known
work-a-round.

if( ( GetWindowRect( whl, wr ) ) &&
      ( GetClientRect( whl, cr ) ) )                      /* window size     
*/
  {
    LONG     xsiz;
    LONG     ysiz;

UpdateWindow( whl );

hdcw = GetDC( whl );
    hdcb = CreateCompatibleDC( hdcw );

if( hbit = CreateCompatibleBitmap( hdcw,              /* create bitmap   
*/
                                       xsiz = wr->right  - wr->left,
                                       ysiz = wr->bottom - wr->top ) )
    {
      SelectObject( hdcb, hbit );

AdjustWindowRect( cr, style, FALSE );             // border information

BitBlt( hdcb,                                     /* dest'n DC      */
              0,                                        /* dest'n X pos   */
              0,                                        /* dest'n Y pos   */
              xsiz,                                     /* dest'n Width   */
              ysiz,                                     /* dest'n Height  */
              hdcw,                                     /* source DC      */
              cr->left,                                 /* source X pos   */
              cr->top,                                  /* source Y pos   */
              SRCCOPY );                                /* operation mode */

SetClipboardData( CF_BITMAP, hbit );              /* set the data   */
    }

DeleteDC( hdcb );
    ReleaseDC( whl, hdcw );
  }
