I am using Lightroom Classic Version 7.3.1 (1167660) on a laptop running:
Windows 10 Home
OS build 17134.81
As I haven't used my Lightroom since 23 May and Windows updated on 28/05/18, I am suspecting it is the problem? The screenshot shows exactly what I see when I go into the develop mode, my photos show fine in Library mode.
I would really appreciate help to get this sorted as this software is crucial to my work. I pay a monthly subscription for this software.
Go to Edit > Preference > Performance, and uncheck Use graphics processor.
Updating your graphics driver may make it possible to work with the graphics processor (GPU) enabled.
That did it! Thank you so much @
