Can you please post a screenshot for the same.
also, let us know the Lightroom and OS version you are using.
Have you tried to disable the GPU support?
Not sure how you do it.
Oh, I am using Lightroom CC (latest version) and Mac OS X El Capitan.
Try and delete the Preview Cache.
It is located in the same folder as the Lightroom Catalog. The preview cache name ends with Previews.LRDATA and should be deleted. Do not confuse this with *.LRCAT, which should not be deleted.
Hi I too have the same issue.
I tried deleting the previews.LRDATA but the problem still remains.
If it helps my work flow is this:
My photos are were raw but then converted to .dng files apart from others that are jpeg, These files are on a NAS drive and i'm connected via wifi.
The catalogues files are stored locally all photos are on the NAS (referanced)
If you are using Lightroom 6, then try turning off the Graphics Processor from the Lightroom preferences.
Go to Lightroom Preferences from the Edit menu
Click on Performance tab
Uncheck the Graphics Processor
Now, if the above solution didn't help, then try import some images from the local drive and check how they looks, as we don't recommend to network drive while working on Lightroom.
Let us know the outcome.
I'm using Lightroom CC does this still apply?
