Layer display problem

[stéphanief596921]

Hello,
First of all, I'm not English-speaking, so sorry for the mistakes.
I'll try to explain my concern:
Since yesterday I loaded the latest version of Photoshop (21.2) and I notice a strange behavior of the software.
When I move a slap, it remains visible and seems to "duplicate" itself, so I end up with a kind of overlap that is very annoying. (see attached picture)
But when I hide another layer this overlay disappears.
I have the same problem with my shadows...
It's really embarrassing and I don't understand where it comes from...
Thank you for your help

Hi

Go into preferences and disable lecgacy compositing if it's enable and restart Photoshop
