My screen is flickering/clignotement/scintille/blinking (S2722QC)

Hi!

My screen which is almost brand new, is flickering at some random moments. The blinking is of no color, it's really like an interference. It also seems to depends on what app are on my screen? Sometimes I can't barely see it, sometimes it's overwhelming.

I'm connected thru usb-c on my mac. I've tried changing the resolution, changing the refresh rate, changing of usb port, pluging the monitor on a power-bar or directly into the wall, etc.

Maybe there are some specific specs to optimise? Can someone help?

Monitor firmware: M3B201
