Photoshop 21.2 lags or runs slowly and not updating the image correctly.

Question

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 PC with 32 Gb of Ram so theoretically it should not be a problem...Any clues about how can I solve this? Thank you.

Hi there,

Sorry that Photoshop 21.2 is running slowly, lagging and showing you duplicate images.

The problem related to duplicate/shadow image is a known issue and our engineering team is looking into it. The workaround is to make sure "Legacy Compositing" under Preferences > Performance menu is unchecked.
