Crop Issue in Lightroom

[toms57283429]

Hi,

When I crop an image in Lightroom it shows on the screen as blurred. If I view the photo in Loupe view the photo looks sharp again. But in Develop mode it goes blurry. 

Atttaching 2 screenshots which I hope demonstrate the issue.

I assume I have a setting wronfg rather than this being a glitch.

Any help would be great, thanks.

(all software up to date btw)

If you disable GPU in preferences, is there any difference or better?

Amzing thanks, yes that worked. I have set the GPU to 'off'. Or should I choose 'custom'?

Thanks so much.

Good news, bad news (kind of). 

If turning OFF the GPU works, it's a GPU bug, and you need to contact the manufacturer or find out if there's an updated driver for it. This is why disabling GPU is an option as more and more functionality moves to the GPU in newer versions of many Adobe products.

On Mac, the updates are part of the OS updates. 

Yes, you could try altering your settings to custom but ideally, you'll get an update that fixes the 'bug' in your GPU.
