Comment 1 Maugre 2021-05-28 15:52:14 UTC 
Was this on a Wayland session, or was it X11? I've had similar (unresolved) Gwenview crashes for months when dragging an image when on Wayland session that don't occur on X11, though my system uses AMD graphics.
Comment 2 Andrew Shark 2023-08-22 21:28:34 UTC 
I cannot reproduce. I can drag the displayed image from Gwenview and drop it for example to Dolphin.
I will close as Worksforme. If it still happens to you, please reopen.
