Moving objects or images lagging

[vicstat]

I recently updated all my Adobe apps and Photoshop started lagging when I move objects.  For example, if I move a bitmap logo or any object from point A to point B, it shows the logo/image in both points, A and B. I didn't duplicate the object I just changed the positioning. It's really painful, especially for digital painting. I am using an iMac with 32 Gb of Ram so theoretically it should not be a problem...Any clues about how can I solve this? Thank you.

Switch off Legacy Compositing Edit > Prefs > Performance. Then restart PS. This seems to clear up the problem.
