I have problems with Lr since the new 7.2 version.
I have no error message, everything is going well but after several minutes, Lr works very slowly, displaying photo is very long (when it works). At the end it's impossible to work.
And "x", "u" shortcuts, don't work.
So, what I did, trying to find the problem :
Verified Lr, Win 10, graphic card pilot were updated-->checked
Disabled graphic card in Preferences-->same problem
Disable graphic card in system-->same problem
Reinit Lr preferences -->same problem
Reinstall Lr-->same problem
This https://helpx.adobe.com/lightroom/kb/issues-lightroom-classic-7-2.html -->same problem
This is an issue win Lr 7.2, because before I haven't these problems
Do you have any idea?
You need to describe the type of things you are doing (in lots of detail) when this slowness happens.
Also please tell us the make and model of the CPU in your computer; the size of the photos that your camera takes in pixels or megapixels (do not tell me megabytes); and the size of your monitor in pixels (do not tell me inches or centimeters)
in the meantime, dell push an update and everything works fine now.
