Artefact on virtual machine using a dedicated rtx3080

Hi there,
we are using a ESX 8 with a windows 10 machine. User log on it trough tse. There a 10 users who share the graphic card. Every user got the same issue.
The VM has a RTX3080 dedicated to it.
We have graphical issue on it, but not one multiple screen.
The hardware has been test and is ok.
We applied at least 4 driver update for the past 6 month wich doesn’t change anything
does anybody have an idea ?
