lightroom classic cc flickers when I crop

[katiem71122678]

I got a new computer last week, installed creative cloud and every time I crop in lightroom classic cc it flickers to the previous image and then to the one I'm working on. I have the newest version and my computer is fully updated. What can I do to fix this?

I'm on a 2017 iMac Retina 5K - 27 inch - MacOS 10.13.4.  Running Lightroom Classic CC 7.3.

I'm getting the same thing.  When I resize (crop) an image I've been working on in the Develop module, it shows the last image I cropped and then quickly changes to the current image I'm wishing to crop.

Tried dumping the LR caches "Performance > Purge Cache" for both stills and video.  No go.

Ideas?

This is possibly a conflict with your graphics card. You could try updating your graphics card driver to see if that helps. If not then you could try going to the Lightroom preferences, performance tab, and unchecking the graphics processor option to see if that resolves the issue.

Preferences > Performance > UNCHECK "Use Graphics Processor" DID correct this on my iMac above.

Thanks!

That's interesting to me. I am not a Mac person, have never used one. But my understanding is that the graphics processor support was introduced primarily to support the high-resolution monitors. You might check to see if there is an updated driver for your processor and see that improves the situation. If not you can always disable it again.

The strange thing is that even if the graphics card is listed (I have an imac 2017), only deselecting the option of the graphics processor solves the problem ... that is not a solution, but a paliativo as it is a bug of Lr

Thank you! I unchecked the graphics processor and it seems to be working now! Yay!

Go to preferences >> performance - At the bottom, uncheck "Generate previews in parallel"
