Image quality in editor - jagged edges

I have this same issue. My display is ok as it renders the same files perfectly in other applications.  It is only in the editors that the interpolation is awful. 

stuarto46527878  wrote When I open an image from the organiser into the editor, the image displayed is of much lower quality. It looks more pixelated and the edges are significantly jagged. This is even before any changes have been made. If I edit the image, say with some filters, and then save it, it looks fine again in the organiser view. Is this some sort of cut-down preview for performance purposes? I cannot see any preference to improve the preview quality.

In the editor, the only situation in which you can judge the edges is when displaying at 100% pixel view. Zooming to 50%, 25% or 12.5% also allows a good interpolation for  viewing.

What you are seeing is also much more visible if your display has a low resolution.
