Just updated to LR v 11.2 and LR is now slow. In Library...I can not select anything, there is a long delay. Once selected - can not do anything, ie sent to PS, rename etc.
The first thing that you should try is to switch off the GPU support from the Lightroom preferences and check if that helps to fix the issue.
Go to Lightroom > Preferences > Performance tab > Uncheck "Use Graphics Processor" > Restart Lightroom.
If Lightroom doesn't start correctly the please see "Solution 2" in the document behind the second link.
Another step is to try to reset the Lightroom preferences.
Alt shift seem to solve issue for the time being....Thanks.
Well that did not last long....back to same issue...can not select anything in library, takes awhile. Turned off the gpu, same behavior.
Which plugins do you have installed?
Please try to deinstall the plugin "proshow". It seems this plugin has a problem and doesn't work correctly.
