This bug make reporting bugs in desktop-grid KWin-effect harder, because i cant easily make an image-proof of bug in this effect. There is no known sane way to make proper screenshot in desktop-grid view AFAIK.

I'm afraid this is an X11-specific limitation that cannot be fixed. It can however be worked around if you use the timer functionality in Spectacle to take the screenshot before activating Overview.

On Wayland, it works as you expect.
