RX 6700XT - blinking with displayport and not in HDMI

Hello

I have just received a 6700xt and I have a problem when I am connected using displayport only. My screen flashes at the bottom (see video below). This phenomenon only occurs in Displayport and not in HDMI, under Windows but also in the BIOS.

Here is my configuration:

i7 8700k
MSIZ370 KRAIT Gaming motherboard
32GB RAM
600W gold power supply

Here are the actions I've already taken:

Test "power supply" in OCCT, passed
Change displayport cable
Update bios
swapped the power cables, making sure there were two separate ramps.
Tried several AMD drivers
Try 8bit and 10bit colour mode.

No improvements, any ideas?
